Hand-feeding a flock twice a day stops being a charm once you pass about thirty birds. You are out at dawn throwing scratch, out again at dusk, and any feed that hits the ground between those two visits is feed the mice get instead of the hens. That is the whole argument for an automatic chicken feeder: it stores the feed sealed and dry, and it lets the birds eat on their own schedule while you get on with the rest of the day.
For large flocks specifically, the decision is not really about a single machine. An adult hen eats roughly a quarter pound, about half a cup, of feed a day, so thirty birds burn through seven and a half pounds every twenty-four hours and fifty birds get through twelve. Capacity matters, but the number of feeding spaces matters more, because one shared trough means the bottom of the pecking order gets shut out and then eats whatever hits the ground. The keepers we trust most run two or three smaller feeders spread around the run rather than one giant one bolted in the middle.
Over the past season we worked through twelve automatic feeders, from a 40 lb galvanized treadle to a 250 lb app-controlled hopper, and set them against the questions large-flock keepers actually ask: how long can I leave, what keeps the rats out, and how many ports do I need before the dominant hens start guarding them. The answers are in the reviews below, and the same scheduling logic applies whether you are automating [pet feeding at home](https://irlentwincities.com/best-automatic-pet-feeders/) or feeding a flock of fifty.

1. OverEZ 50 lb Gravity Feeder – Best Overall for Large Flocks
OverEZ Chicken Feeder – Holds 50 Pounds of Feed – Inside or Outside Hen Coop – Large Gravity Fed Automatic Poultry Dispenser – No Waste Rainproof Design
50 lb hopper,
3 no-waste ports,
UV-stable plastic,
22.75 x 12.5 x 16.25 in
Pros
- Holds 50 lb so refills stretch out
- Feed ports stop soiling and spilling
- Recessed rain channel keeps feed dry
- Wide mouth allows refilling on the ground
- Works indoors or out
Cons
- Only three feeding spaces
- Plastic body is chewable by determined pests
The OverEZ is the one we kept coming back to during this roundup, and the reason is unglamorous: at more than 1,700 reviews it carries by far the largest body of owner feedback in this list, on a design that suits the way large flocks actually feed. Fifty pounds is roughly a week of feed for a thirty-bird flock at a quarter pound per hen per day, which means one trip to the feed store every week instead of two hand-feeding runs every day.
It is also the easiest of the big feeders to service. The wide-mouth opening lets you tip the whole unit onto its side and scrub it out on the ground, which matters more than it sounds when you are dealing with fifty pounds of feed and a wet, muddy run.
The design detail that earns its keep in rain is the recessed channel. Feed sits under an overhanging port lip, so runoff runs down the outside instead of into the grain. Owners in wet climates report feed coming out of this feeder dry after heavy rain, and the UV-protected plastic means the body will not chalk and crack the way cheap resin does after two summers of full sun.
For a large flock, the honest limitation is throughput rather than capacity. Three birds can eat at once. With thirty hens that means queueing, and a queue is exactly where bully hens set up shop. Our advice is to run two of these in different corners of the run rather than one in the middle, which is also what experienced keepers on backyard poultry forums consistently recommend for flocks past about twenty-five birds.
How it handles a 40 to 50 bird flock
Fifty pounds covers a forty-bird flock for about five days in summer and closer to a week in spring. You will be refilling twice a week, and because the fill is a ground-level wide-mouth pour, one person can do it in a couple of minutes.
Run two of these and you have a flock that can go a full weekend without you touching it. That is the configuration we recommend for anyone traveling regularly.
Where it falls short
Three ports is fewer than most metal rivals here, and the body is plastic, so a determined raccoon or squirrel can chew it where a galvanized feeder would simply shrug. If you have a documented rodent or squirrel problem, step up to a treadle design rather than trying to out-wildlife a plastic hopper.
2. RentACoop 50 lb Galvanized Trough Feeder – Best for Ducks, Geese and Mixed Flocks
RentACoop 50lb Gravity-Fed Metal Trough Feeder with Lid & Rain Cover
50 lb galvanized trough,
Side view window,
Lift-out grate,
Magnetic lid and rain hood
Pros
- Heavy galvanized steel with stainless hardware
- Viewing window tracks feed level
- Grate lifts out for fast cleaning
- Handles pellets
- crumbles and scratch
- Removable rain hood
Cons
- Needs a level mounting position
- Not suitable for chicks
RentACoop built this one out of galvanized sheet metal with stainless steel screws, and you can feel the difference the first time you try to shift it. A sturdier build than anything molded in this lineup, and it handles more than hens. Owners use it for ducks, geese and other waterfowl as well as chickens, which is why it earns our nod for mixed flocks.
Unlike a port-style feeder where the port is fixed to a height, this is a trough design, which means more of the feed surface is available and a wider range of bird sizes can reach it. The grate is designed to clip up and out, so you can remove it for cleaning or leave it out entirely when the birds are large enough to eat without raking feed across the ground.
The side window is the feature we would not give up. On a feeder holding fifty pounds, you do not want to lift the lid every day to check the level, and the window lets you walk past and read the remaining feed at a glance. That single convenience is what makes this an easy large feeder to keep stocked on a tight schedule.
Galvanized construction also shrugs off weather. Owners leave these out through wind and rain year round, and the smooth interior means feed does not stick to the walls the way it does in molded plastic, which cuts both mold risk and cleaning time.
Why mixed-flock keepers pick this one
Ducks and geese eat differently from hens and will happily tear feed out of a narrow port. The trough layout and the lift-out grate let you adapt the feeder to whatever is in the run without buying a second unit.
It is also the better pick for very mixed ages, since pullets and adults can both reach the same feed surface instead of the smaller birds being left out.
What to watch for
A trough needs a more level position than a freestanding port feeder, so plan the spot before you fill it. It also will not work for chicks, so if you are brooding while the flock is out, keep a separate small feeder for them.
3. Grandpa’s Feeders 40 lb Treadle Feeder – Best for Rodent Proofing
Grandpas Feeders Automatic Chicken Feeder – 40 lbs No Waste Poultry Feeder, Rat Proof & Rodent Proof Treadle Chicken Feeder, Galvanized Steel with Lid, Feeds 6-12 Chickens up to 10 Days
40 lb galvanized steel
Treadle-activated lid,
Anti-flick grill,
Feeds 6-12 birds up to 10 days
Pros
- Lid opens only under a bird's weight
- Ends rat and rodent problems
- Anti-flick grill cuts scratch waste
- Stays dry in heavy rain
- Anti-roost side guards
Cons
- Needs a training period
- Flat lid invites roosting
- Slamming lid can startle birds
- Crumble feeds may need the box shaken
Grandpa’s Feeders is the name that comes up most often on poultry forums when anyone asks about rodent-proof feeding, and after working with this unit the reason is obvious. The treadle is a pedal that only depresses under the weight of a chicken, so the lid stays shut when nothing is standing on it. Rats, mice and sparrows cannot open it. That single mechanism solves the pest problem more decisively than any amount of latches or lids on a gravity hopper.
Multiple owners report that after switching to this feeder, a rat problem that had been costing them feed for years simply ended. It is one of the clearest pest-exclusion stories in this roundup, and it is why this is the pick we recommend whenever the run sits near a field, a barn, or a compost pile.
The anti-flick grill inside is the second reason to care. Chickens love to grab a beakful of feed and flick it sideways, and that flicking is the single largest source of waste in a backyard flock. Owners report scratch waste dropping sharply and feed bills following. Add the side guards that stop side-feeding, and you have a feeder designed from the ground up around reducing what lands on the ground, which also means less for rodents to live on.
Capacity is rated at feeding six to twelve chickens for up to ten days. For a large flock, plan on two or three of these spaced around the run rather than one, and the same 30 to 100 bird logic from our capacity section applies.
When the treadle works in your favor
If you travel, this is the most secure feeder in the roundup. One owner went away for a week and came back to a feeder still holding feed, and the pedal lock lets you close it down entirely overnight so nothing can get at it. Galvanized steel also stayed bone dry through heavy wind and rain in owner reports.
The training system is usually faster than advertised, with birds often working the pedal within about a week rather than the suggested two.
What to watch for
Two real cautions. First, the treadle needs a minimum bird weight, so bantams and silkies cannot actuate it at all. Second, and more important for a large flock, if you set the release weight low enough for small birds you have also lowered the threshold a raccoon can reach. Keep the release weight set for full-grown hens if predators are a concern, and never drop it for the sake of a few bantams.
Reviewers also flag the flat lid top as a roosting perch, and note that the fast-slamming metal lid can startle birds or catch a comb as it closes. Some crumble feeds will not gravity-refill the trough cleanly and need the box nudged forward.
4. RentACoop 40 lb Automatic Treadle Feeder – Best for Mixed Flocks with Small Birds
RentACoop Automatic Treadle Chicken Feeder, Rat Proof No Waste, 40 lb
40 lb galvanized metal,
Adjustable feed-flow plate,
Detachable step weight,
Anti-roost lid
Pros
- Keeps rats and wild birds out
- Holds ten days for nine birds
- Trains quickly with supplied screws
- Anti-roost lid stops bird on top
- Step weight works for bantams
Cons
- Squirrels learn to open it
- Lid latch gap admits wind-driven rain
- Hot treadle plate in full sun
This is the treadle to buy if your flock is genuinely mixed, with bantams or silkies alongside full-sized hens. The detachable step weight is the reason: you can load the pedal so a small bird can trigger it and the mechanism still shuts out anything lighter than that. Grandpa’s does not offer that adjustment, and for a mixed flock it is the difference between a feeder everyone uses and a feeder the small birds are shut out of.
It is also the most adjustable of the treadles here. The internal feed-flow plate raises for pellets and lowers for crumble and grains, which matters in a large flock where you might be switching feed types across the year, and the perforated step sheds rain and grips well on uneven ground.
Owners running larger flocks report using two of these across two separate runs, with thirty birds, and cite zero rodent problems. The safety blinders push birds to feed from the front only, which cuts the side-spill problem that plagues open troughs. Rental company customer service is also genuinely good, with replacement parts sent quickly after one unit arrived damaged.
Capacity works out to about ten days of feed for nine birds on the manufacturer figures. For a fifty-bird flock, that is roughly six feeders, which tells you something about how large-flock keepers actually deploy them: spread out, not clustered.
Where it earns its place in a large run
Two of these in opposite corners of a run eliminate the single-point bottleneck. Subordinate birds have an option that dominant hens cannot patrol, and you have measured confidence that the feed is sealed against mice and sparrows between meals.
The optional step lock is worth using at night, when wild birds are most active and the flock is roosting anyway.
What to watch for
Squirrels are heavy and clever enough to learn to operate a treadle, so in a squirrel-heavy area you will want hardware cloth around the run. Some units also arrive with the lid not sitting where the latches engage, which leaves a permanent gap that lets wind-driven rain in, and the metal treadle plate gets hot enough in direct sun that it needs shade.
Square tubing burrs may need filing and the self-tapping screws can be hard to start, so allow yourself an unhurried assembly. One owner’s flock simply refused to use it, which is a real outcome with treadles and worth knowing before you commit.
5. Tgeyd 95 lb 10-Port Galvanized Feeder – Best for Very Large Flocks
95 lb Chicken Feeder with 10 No-Waste Ports – Extra-Large Galvanized Metal Poultry Feeder with Adjustable Height Heavy-Duty Stand – Outdoor Feed Box for Chickens, Ducks & Geese
95 lb galvanized steel,
Ten angled no-waste ports,
Adjustable-height stand,
23.6 x 12.2 x 25.8 in
Pros
- 95 lb hopper for large flocks
- Ten ports feed many birds at once
- Galvanized steel resists rust
- Height adjusts for chicks to large birds
- Riveted handles ease lifting
Cons
- Bulky footprint for a small coop
- Heavy to reposition when full
At ninety-five pounds this is the largest chicken-specific hopper we tested, and with ten angled feeding ports it solves the throughput problem that limits most other large feeders. Where the OverEZ feeds three birds at once, this one feeds ten. For a flock of sixty or more, that difference is the whole decision.
The ports are angled specifically to prevent feed scattering, so the birds feed through a slot rather than a hole and the feed stays in the box instead of on the ground. That matters twice over for a big flock: less waste on the bill, and less loose feed for rats to sort through.
The adjustable-height stand is the sleeper feature. Feeders with fixed legs force you to buy one feeder for chicks and another for adults, while this one raises and lowers, so a single feeder can serve a mixed-age flock through a whole season. Galvanized steel handles year-round outdoor use without rust, and the locking hinged lid keeps feed dry between fillings.
Seventy-one percent of its reviews are five-star, which is a strong signal for a unit with under 200 reviews. The pattern in the feedback is consistent: people bought it for capacity, and stayed because the port count meant nobody got pushed off the feed.
How we would deploy a 95 lb feeder
Ninety-five pounds is roughly 380 hen-days of feed, so on a sixty-bird flock that is a little over six days between refills. Most people run it as the main hopper in the middle of a large run and pair it with two smaller feeders elsewhere so subordinate birds always have an option.
If you refill on a schedule rather than on empty, a hundred-bird flock gets through a full hopper in under four days, which is a comfortable weekend-plus margin.
What to watch for
Ten ports need floor space. This is a bulky unit and it is not right for a small mobile run or a tight urban coop, and at nearly twenty pounds empty it is real work to move once you have topped it up. Riveted handles help, but plan your fill location before you swing the lid open.
6. BUYYAH 60-90 lb Galvanized Feeder – Best for Leaving the Flock Alone
BUYYAH 60-90lb Automatic Chicken Feeder
60-90 lb galvanized steel,
Waterproof lid,
Suitable for poultry and turkeys,
16.1 x 16.1 x 17.54 in
Pros
- Covers about 20 hens for roughly 15 days
- Weatherproof galvanized steel
- Waterproof lid keeps feed dry
- Handles chickens ducks geese and turkeys
- Also offered in 80lb and 100lb
Cons
- Vague 60-90 lb capacity range
- Heavy at 26.2 lb empty
- No side window to check level
This is the feeder we would trust most for an unattended weekend. The capacity claim is sixty to ninety pounds, and the brand rates it at roughly twenty hens for fifteen days. Even taking the low end of that range, you are looking at a long weekend with no visit, which is the number that matters when you have a job and travel regularly.
The waterproof lid is the simple, unglamorous feature that earns the badge. No rain hood to lose, no latch to line up, nothing to remember except that the lid is down. Galvanized steel takes extreme weather without complaint.
It also handles more than chickens, working for ducks, geese and turkeys, and it comes in 80 lb and 100 lb variants if you need to scale up for a bigger flock. We would treat the second and third numbers as a reason to buy the higher-capacity version rather than to plan around the lower one.
This is a plain gravity feeder, so understand the tradeoff. There is no treadle, which means no mechanical barrier against rodents. The lockable lid helps between fills, but if your problem is rats rather than time, look at a treadle instead.
Capacity planning for weekend coverage
Run the daily math honestly. A twenty-bird flock eats about five pounds a day, so a sixty-pound minimum fill covers twelve days and a ninety-pound fill covers eighteen. That is the difference between comfortable and anxious when you are two hundred miles from home.
Refill before you leave rather than topping off, and check the level the day you get back so you learn your actual consumption rate rather than the advertised one.
What to watch for
The 60 to 90 lb range is genuinely vague, and real capacity depends on pellet size, so weigh the feed you actually buy. There is also no side viewing window, which means every check involves lifting the lid. And at 26.2 pounds empty it is one of the heavier units here, so a full lift is a two-person job in a big flock.
7. HAYOHRT 85 lb 10-Port Feeder – Best for Rainy Climates
HAYOHRT 85-120LBS Capacity Chicken Feeder No Waste 10-Ports Automatic Large Poultry Feeder with Latch & Handle for Chickens Bantams Pheasants Poultry Coop Weatherproof
85 lb metal,
Ten ports with extended rain covers,
Top cover lock,
23.6 x 11 x 24.8 in
Pros
- Feed stayed dry through a wet month
- Cuts feed use measurably
- Holds two to three 40 lb bags
- Keeps wild birds and mice out
- Birds adapted in about three days
Cons
- Sits low for turkeys and large roosters
- Ports narrow for tall combs
- Assembly takes one to one and a half hours
The extended port covers are the reason this one earns its place. Each of the ten ports has an overhang that keeps rain runoff off the feed, and one owner reports that crumble stayed dry inside through a full month after their run lost its cover in a rainy, cold stretch. For anyone feeding a flock through a wet winter, that is the spec that actually matters.
Waste reduction is the other headline, and it is quantified in the reviews. One keeper with twelve hens cut feed use from forty pounds every six days to about twenty pounds over three weeks. That is a real change in the feed bill, and it comes from the no-waste port geometry plus the lid that you tighten down when the birds are not eating.
Pest results are strong for a gravity design. One owner reports no mouse or wild-bird sign over six months, and the top cover lock is a genuine deterrent against weasels and raccoons. Birds here adapted in about three days, after pellets were placed on the port lips, which is the fastest acclimation we saw from a gravity feeder in this roundup.
Owners report it holding two or three forty-pound bags, and the manual and screws are included in the box.
Feeding ten birds without a bottleneck
Ten ports spread across the box means a fifty-bird flock can feed in two waves without queuing, and that is the mechanism that stops dominant hens from controlling the feeder. With extended covers on every port, you get that throughput without losing the rain protection that a flat-lid design gives up.
It is also offered in 5-port, 6-port and 10-port leg-equipped variants, so the same design can scale down if your flock shrinks over winter.
What to watch for
The unit sits low, and owners with turkeys or roosters had to raise it on blocks. The ports are also a little tight for roosters with tall combs, which is worth checking if you keep large Mediterranean breeds. The lid may not sit flush on arrival and can need a plier adjustment, and expect an hour to an hour and a half for assembly, with sharp metal edges during the build that a few owners taped over afterward.
8. TGEYD 50 lb 8-Port Feeder – Budget Pick
TGEYD 50LB Large Automatic Chicken Feeder – 8 Feeding Ports, No-Waste Poultry Feeder, with Adjustable Legs & Locking Lid
50 lb galvanized metal,
Eight feeding ports,
Adjustable legs,
Locking lid
Pros
- Locking lid kept rats and skunks out
- Metal build resists chewing better than plastic
- Holds most of a 40 to 50 lb bag
- Easy to assemble with solid parts
- Available in three colors
Cons
- One reviewer found substantial spillage
- No rubber washers so rain can seep
- Leg height may need changing
- Real capacity under the stated 50 lb
Eight feeding spaces in a fifty-pound galvanized box is a lot of function per dollar, and this is the pick if you are outfitting a large run on a tight budget. The metal body is the important part: owners report that while plastic feeders got chewed and destroyed by rats, the steel box held, and several specifically say the locking lid kept rats, skunks and opossums out of the feed.
For a flock of thirty to forty, the math works. Fifty pounds is about a week at a quarter pound per hen, eight ports means several hens eat at once rather than queuing, and adjustable legs keep the ports off damp ground and match the height to your birds.
Several owners report no scratching of feed out of the ports at all, and assembly is straightforward with undamaged parts in the box. It is also available in orange and silver, which is a minor but real help if you have one already and want the run to look deliberate.
Be clear-eyed about the feedback split though. At a 4.0 average with a meaningful share of critical reviews, this is a competent budget box rather than a standout, and the complaints are specific enough to check before you buy.
Where the budget math works best
Buy this when you want two or three feeders spread around a run rather than one premium unit in the middle. The whole large-flock strategy depends on multiple feeding points, and at this level of cost you can actually afford to follow it. Pair two of these with a treadle for the flock you are most worried about and you cover both the budget and the pest requirement.
Just budget for adjusting the legs once or twice as birds grow, and measure how much feed your brand of pellet actually holds.
What to watch for
The real complaints are spillage and water. One reviewer found it far from waste-free, with substantial feed landing on the ground, and the metal screws and box with no rubber washers mean rain can seep in through the port holes. Buyers also report actual capacity running under the stated fifty pounds depending on granule size. Put it under cover if you are in a wet climate, and expect to adjust leg height as the flock grows.
9. Pawaboo 55 lb Feeder – Best for Monitoring Feed Level
Pawaboo 55LBS Large Capacity Automatic Chicken Feeder
55 lb aluminum-coated steel,
Seven ports with drip trays,
Viewing window,
Tool-free adjustable legs
Pros
- Viewing window shows feed level without lifting
- External drip trays catch spilled feed
- Sloped top deters perching
- Tool-free legs fit different bird sizes
- Coated steel resists rust and chewing
Cons
- Seven ports trails the 8 and 10 port rivals
- Plastic window can yellow with UV exposure
The drip trays are the feature no other feeder in this roundup has. Mounted externally below each of the seven ports, they catch feed that gets flicked or scratched loose, so waste lands in a tray you can empty rather than on the ground where it feeds the local rodent population. For a large flock where even a few percent spillage adds up to real pounds of feed a month, that is a quietly valuable addition.
The viewing window is the other one. On a feeder holding fifty-five pounds, being able to read the level without lifting the lid saves you the daily ritual of opening a box and exposing the feed to weather and pests.
The sloped top is designed to stop birds perching and it drains rainwater quickly, so you get the roost-resistance that a flat or hinged lid gives up, and it doubles as a rain shedder. Adjustable legs span 5.9 to 10.6 inches and adjust without tools, so one feeder handles pullets through full-grown birds as the flock ages through the season.
Aluminum-coated galvanized steel is the right material for this job, resisting rust and resisting the attention of animals that would chew through plain plastic. A lockable lid plus sealed ports keeps feed dry and blocks rodents between fills.
Waste control in a fifty-bird run
Seven ports is fewer than the eight and ten port rivals, so on a very large flock you would want to pair this with a second feeding point rather than run it alone. The drip trays then make the pair work: whatever gets flicked out of either feeder ends up in a tray instead of underfoot.
Capacity of fifty-five pounds covers a forty-bird flock for about five and a half days in summer and closer to eight in spring.
What to watch for
Throughput is the honest limitation, since seven ports means less simultaneous eating than the leaders. The viewing window is plastic, and plastic yellows and eventually cracks with sustained UV exposure, so in a full-sun location expect to replace the window or the unit eventually. Everything else here is solid.
10. GADFISH 55 lb 8-Port Feeder – Best for Muddy or Uneven Ground
GADFISH 55 lbs Large Capacity Automatic Chicken Feeder – 8 Feeding Ports, No Waste Chicken Feeder, Height-Adjustable Legs & Secure Locking Lid for Chickens, Ducks & Poultry
55 lb galvanized sheet metal,
Eight feeding ports,
Tool-free rotating legs,
Conical lid
Pros
- Eight birds feed at once
- Legs rotate to change height with no tools
- Wider base resists sinking in mud
- Conical lid sheds rain and stops roosting
- Extended ports deter other animals
Cons
- Conical lid leaves less fill opening
- Some units arrive with fit or finish issues
Plenty of large feeders sink into wet ground or tip over in mud by the second winter. This one has an increased base contact area specifically to stop that, and if your run turns to soup in January, that engineering detail matters more than another twenty pounds of capacity.
Height adjustment is done by rotating the legs, with no tools and no removal, so you can raise the ports for full-grown birds and drop them for pullets in under a minute. Eight feeding ports serve eight birds at once, and the extended ports are designed to cut waste and discourage other animals from reaching in.
The conical lid serves two purposes at once: it stops poultry standing on top and roosting in the feed, and it drains rainwater after a storm rather than letting it pool. Aluminum-coated galvanized sheet resists rust, harsh weather, and biting animals, and the interior wipes clean easily.
At fifty-five pounds it sits in the same capacity band as the Pawaboo and the eight-port budget boxes, which makes it a straightforward middle-of-the-roundup choice for a flock in the thirty to sixty bird range.
Why the base matters in a real run
A feeder that sinks takes its ports closer to the mud, so feed gets soiled and the bird has to reach into wet litter to eat. That is a hygiene problem and a waste problem at the same time. A wider footprint on soft ground keeps the ports clean and the feeder stable, which is why this one suits low, wet runs where taller narrow-legged feeders do not.
Combined with eight ports, it works as a mid-sized backbone feeder for a flock around forty birds, paired with one smaller feeder elsewhere in the run.
What to watch for
The conical lid leaves less usable fill opening than a flat or hinged lid, so top-ups are slightly slower and you are less likely to see the feed level. There is also an 11 percent share of one-star reviews, which points to some units arriving with fit or finish problems. Inspect the box and screws on arrival rather than assuming.
11. CoopWorx 80 lb Rotomolded Feeder – Best for Near-Zero Feed Waste
CoopWorx Poultry Feeder 80 lb Capacity – Adjustable Height Chicken Feeder – UV Stable Rotomolded – 8 Soft-Touch Ports – Roost-Resistant Lockable Lid – Made in USA
80 lb rotomolded plastic,
Patented funnel design,
Eight soft-touch ports,
Port height 9 to 18 in
Pros
- Funnel design uses nearly all the feed
- Cut waste and bottom spoilage
- Feed stayed dry through a downpour
- Roost-resistant lid needs no cleanup
- Parts fit together with no filing
Cons
- Top of the price range here
- Lowest leg setting still excludes bantams
- Rotomolded plastic is chew-prone to squirrels
Hoppers with flat bottoms tend to leave a foot or two of feed in the corners that never flows and eventually spoils. The patented funnel in this one is designed to pull the feed down so that almost all of it is usable, which means less waste and far less mold in the bottom of the hopper. If your feed bill is the thing you most want to cut, that is the mechanism paying for the higher spend.
It is the only Made in USA unit in the lineup, and the build quality shows in the details: parts fit together cleanly with no filing, and setup is quick and intuitive. A keeper with thirty-plus birds reports that the flock fed itself each morning instead of waiting at the coop door for you to arrive with a bucket.
The roost-resistant hinged lid stays attached to the unit while you fill or clean, so you are not holding a loose lid in one hand and a feed scoop in the other with fifty birds trying to help. A lockable lid section adds pest protection on top of that, and adjustable legs set port height from about nine to eighteen inches.
One owner with fourteen birds reported that crumble stayed dry inside after a downpour, which is not a given for a plastic hopper in open ground. Customer service here was the best in the group, with a missing leg extension sent out within a week over live chat.
When waste reduction justifies the spend
Run the numbers before dismissing it. A fifty-bird flock on crumbles loses a measurable amount to spoilage and flicking in any hopper; if you are buying feed by the bag, a funnel that uses nearly all of it pays for itself over a season, and the eighty-pound capacity means refills roughly every six or seven days in summer.
The eight soft-touch ports also let multiple birds feed at once, which reduces the number of feeders you need to spread around the run.
What to watch for
This is the most expensive feeder in the lineup, and it is a large step up from a basic gravity box, so it only makes sense if waste is your actual problem. The lowest leg setting is still high enough that bantams and other small breeds cannot reach, and rotomolded plastic, while rust-proof and UV-stable, is lighter and more chew-prone than galvanized steel, with a report of a squirrel chewing on one unit. One owner also saw hens drag out large amounts of feed and had ten pounds pour out when opening the lid.
12. Moultrie 250 lb App-Controlled Feeder – Best for App-Controlled Feeding
Moultrie 250 Lb Pro Hunter III Tripod Feeder – Bluetooth App Control
250 lb polymer hopper,
Bluetooth control to 300 ft,
Ten daily feed events,
36 x 36 x 72 in tripod
Pros
- App scheduling removes fixed visits
- Ten daily events with adjustable RPM
- 250 lb hopper with ground-level fill
- Stable and rugged in exposed positions
- Locking lid blocks varmints and moisture
Cons
- Designed for deer
- not chickens
- Varmint damage reported
- No cage included so motor is exposed
- Battery and solar panel sold separately
We want to be straight with you about this one: the Moultrie Pro Hunter III is a deer and game feeder, not a chicken feeder, and it is in this roundup because large-flock keepers keep doing the same thing with it. One owner reports cutting feed costs roughly in half by running it for chickens, using the scheduled dispense to control how much goes out and when.
It is the only motorized, timer-driven option in the group, and that is genuinely a different category from every other feeder here. Instead of feeding on demand, the motor drops a measured portion at set times, up to ten events a day, with the spin plate set high, medium or low to tune the volume. You control it from up to three hundred feet over Bluetooth, or pair it with an Edge 3 Series camera for cellular remote control with no subscription.
The capacity is the other headline. A two-hundred-fifty-pound polymer hopper with a six-foot fill height means fewer trips, less scent, and undisturbed feeding patterns. In our [smart feeder guide](https://irlentwincities.com/best-smart-pet-feeders/) we cover the scheduling side of this kind of hardware in more depth, and the same remote-monitoring logic applies here.
It is also genuinely tough. It is stable on exposed ground and owners report it withstanding repeated deer rubbing and even two bear attacks, which tells you something about the chassis. The locking lid keeps varmints and moisture out between fills.
Where scheduled feeding genuinely helps
Timed dispensing stops the constant trickle of feed that invites wild birds and rodents to loiter at the feeder all day. If your main problem is theft rather than waste, moving from on-demand to set mealtimes removes most of the exposure window. It also lets you control portion size, which matters if you are moving a flock onto a controlled feeding program.
Two hundred fifty pounds is about a thousand hen-days of feed, so on a hundred-bird flock you would only need to refill it roughly every ten days.
What to watch for
Read this one carefully. It is built for deer, and the motor is completely exposed, with no varmint cage included. Owners report squirrels and raccoons chewing a hole in the hopper and pulling wiring loose, and aftermarket cages redirect the feed under the feeder rather than outward, which defeats the purpose. Bluetooth range is limited, the in-app feed estimator is not accurate, and measured capacity came in at two hundred to two hundred twenty-five pounds rather than the advertised two hundred fifty. The six-volt battery and solar panel are both sold separately.
How Many Feeders Does a Large Flock Actually Need?
Start with the math, then apply the bottleneck rule. An adult hen eats about a quarter pound, roughly half a cup, of feed per day. Multiply by your bird count, divide by hopper capacity, and you have your refill interval. Then remember that capacity only tells you how long the feed lasts, not whether every hen can reach it.
Here is the mapping we would actually use. Assume a mid-sized hen, average feed, and normal seasonal consumption.
15 to 20 birds: one 40 to 50 lb feeder. A single feeder covers four to five days, and you do not need more feeding spaces than that for a flock this size.
25 to 30 birds: two feeders of 40 to 55 lb each. Thirty hens at a quarter pound a day burn about seven and a half pounds daily, so a fifty-pound hopper is refilled roughly every seven days. Two feeders also solves the bully-hen problem before it starts.
40 to 50 birds: two 50 to 60 lb feeders plus one smaller unit. This is the range where spacing starts to matter more than capacity. Put feeders in different areas of the run so no single bird can patrol all of them.
60 to 75 birds: one 80 to 95 lb ten-port feeder plus two 40 to 55 lb feeders. The big unit carries the volume and feeds ten birds at once, and the smaller ones give the bottom of the pecking order an unguardable option.
100 birds and up: three or more feeders of 50 lb or more, spread across the run or split between separate buildings. Experienced keepers running flocks in the hundred-bird range consistently describe a setup built from multiple smaller feeders rather than one giant one, and that consensus is the single most useful piece of advice in this roundup.
The rule of thumb underneath all of that: aim for at least eight to ten simultaneous feeding spaces per twenty-five birds, and never let all your feed sit behind a single opening. One reviewer of the feeder we rate best overall made exactly this point when noting that its three ports limit how many birds can eat at once, which matters for large flocks.
Buying Guide: Picking an Automatic Chicken Feeder for 30 to 100 Birds
Understand the three mechanism types. Gravity feeders hold feed in a covered hopper and let it slide down as birds peck, with a grill or baffle limiting spillage. Treadle feeders add a step plate that only opens under the weight of a bird, which mechanically excludes rats and wild birds. Motorized feeders drop a measured portion at set times. Gravity is the most forgiving, treadle is the most secure, and motorized is the most precise and the most exposed to wildlife.
Pick the pest answer first, because it narrows everything. If you have rats, mice or wild birds, a treadle is the only real answer, and you need to set the release weight for full-grown hens. If squirrels are the problem, treadles can eventually be defeated by them, so add hardware cloth. If theft is occasional, a locking gravity lid handles most of it. Same principle as the [automatic feeder scheduling options](https://irlentwincities.com/best-automatic-dog-feeders/), just with a different animal causing the trouble.
Count ports before capacity. Ports are the feeding spaces. A fifty-pound hopper with three ports is worse for a forty-bird flock than a fifty-pound hopper with eight, because birds queue and dominant birds guard queues. For a flock past thirty, treat eight or more ports as a requirement rather than a nicety.
Check the build against your weather. Galvanized steel with stainless hardware is the standard for year-round outdoor use. UV-stable or rotomolded plastic will not rust but will eventually fade, yellow and crack, and it is easier for squirrels to chew. If your run stays wet, prioritize extended port covers or a recessed rain channel over raw hopper size, and note that budget boxes with metal screws and no rubber washers can take on water at the ports.
Match feed type to mechanism. Pellets and crumbles flow well through gravity ports. The RentACoop treadle goes further with an adjustable internal feed-flow plate, raised for pellets and lowered for crumble and grains, which matters across a year of changing feed. Some crumble feeds do not gravity-refill a treadle trough cleanly and need the box nudged forward, and wet fermented feed is not a good candidate for any dry hopper. Experienced large-flock keepers who use fermented feed typically put it in separate bowls or gutters rather than an automatic feeder.
Budget for seasonal swings. Hens eat less in hot weather and more in cold weather, so a feeder that looks like it will last ten days in July may last closer to fourteen in January. Plan your refill schedule for the worst case, and never leave a flock relying on a single feeder if you travel in the off season.
Watch the reach, not just the flow. Narrow ports scrape the combs and wattles of large roosters and Mediterranean breeds, and ports set too high shut out pullets, which matters constantly in a mixed-age flock. Adjustable legs solve this properly. The ten-port feeders in this roundup are the ones reviewers most often flag as tight for tall combs.
Expect to train treadles, and allow real time. Both treadles here ship with training screws or a three-phase training setup. Most flocks work it out in about a week, and some hens never learn at all. For the first few days, hold the lid or pedal open so birds find the feed, and put feed on the treadle itself if they are hesitant. One owner of the RentACoop treadle had a flock that refused it entirely, so keep a backup plan for the first fortnight.
Know when to skip an automatic feeder. If you keep eight birds or fewer, a simple hanging gravity feeder or even a scoop does the job and costs a fraction as much. The economics only work when you are buying in bulk and refilling by the bag. The same applies to a two-bird flock of bantams, where a treadle simply will not function.
Frequently Asked Questions
What is the best large chicken feeder for a flock of chickens?
The OverEZ 50 lb gravity feeder is the best overall for large flocks, holding 50 lb, using a rain-shedding port design, and being simple to refill and clean on the ground. For rodent problems specifically, the Grandpa’s 40 lb treadle is the better choice, since its pedal-operated lid keeps rats and wild birds out. Run two of whichever you pick rather than one, spaced around the run.
What is the best automatic feeder for a chicken farm?
For a flock of 50 or more birds, capacity and port count matter most. A 95 lb ten-port galvanized feeder carries the volume and feeds ten birds at once, and you pair it with two smaller feeders so subordinate hens have an unguardable option. Experienced large-flock keepers consistently report that multiple smaller feeders outperform one giant feeder.
What is the best treadle chicken feeder?
The Grandpa’s 40 lb treadle is the best-known and most proven, with the strongest reports of eliminating rats and cutting scratch waste thanks to its anti-flick grill and full-coverage lid. The RentACoop 40 lb treadle is the better pick for mixed flocks because its detachable step weight lets bantams and silkies trigger the pedal, and its adjustable feed-flow plate handles pellets or crumble.
What are the drawbacks of using a treadle feeder?
Treadles need a training period of days to weeks, and some hens never learn, which can leave part of a flock unfed. They require a minimum bird weight, so bantams and silkies cannot operate them unless a step weight is added. A raccoon is heavy enough to trigger a treadle set to a light release weight, so keep the weight set for full-grown hens. Reviewers also report startled birds, lids that catch combs, and assembly burrs.
How long does a Grandpa’s feeder last?
The 40 lb model is rated to feed six to twelve chickens for up to ten days, and owners report returning from a week away with feed still in the unit. The galvanized steel body is built for years of outdoor use in any weather, with owners reporting it staying dry through heavy rain and wind. Several keepers describe it as a long-running original brand they have returned to after years.
Do automatic chicken feeders keep out rats and wild birds?
Treadle feeders do, reliably, because the lid only opens under the weight of a chicken, which excludes rats, mice and sparrows. Gravity feeders deter theft with locking lids and extended ports, but a determined squirrel or raccoon can still get in, and owners report squirrel damage even to treadles over time. In a squirrel-heavy area, add hardware cloth around the run regardless of feeder type.
How much feed does a chicken eat per day?
An adult hen eats roughly a quarter pound, about half a cup, of feed per day, and a little less in hot weather with more in cold weather. So a 30-bird flock needs about 7.5 lb daily and a 50-bird flock about 12 lb, which means a 50 lb hopper on a 30-bird flock is refilled roughly weekly. Divide your bird count by four pounds per bird per week to estimate weekly feed needs.
Final Verdict: Best Automatic Chicken Feeders for Large Flocks in 2026
For most large flocks, the OverEZ 50 lb gravity feeder is the right buy, and we rate it the best automatic chicken feeder for large flocks in 2026 because it balances the three things that actually matter: proven capacity, a port design that keeps feed out of the rain and off the ground, and refilling that anyone can do in a couple of minutes. Run two of them instead of one.
When pests are the problem rather than convenience, the Grandpa’s 40 lb treadle is the clear answer, and it is the feeder most often named on poultry forums for keeping rats out. If your flock is genuinely large, pair it with a 95 lb ten-port unit so you have both security and volume. And if you travel every week, a two-bird weekend becomes a problem only with a single feeder, not with two.
Whichever you choose, size the flock first. A quarter pound per hen per day, a feeding space for every ten to twelve birds, and never one opening for the whole run.
