A treadle chicken feeder keeps feed under a lid that opens only when a hen stands on a platform. It is worth buying for an adult flock that has rats, wild birds or rain at the feeder, and it is a poor buy for chicks, very light birds or a flock whose only problem is spilled feed. Expect to pay $65 to $240 on the pages I checked, and plan on about two weeks of training.
Short answer
Yes, for adult hensif your lightest bird outweighs the trigger and you can spend about two weeks training
A treadle feeder shuts its lid whenever no hen is on it, which helps with wild birds, rain and some pests. No maker promises it stops every rat. Check the activation weight before you buy.
How treadle feeders work
A treadle feeder is a feed box with a weighted lid that a platform lifts when a hen steps on it. The lid drops when she steps off, so feed stays closed for everything lighter than the activation weight. Grandpa’s Feeder lists approximate activation weights of 14 oz (500 g) for its Standard model and 2 lb (900 g) for its Large (maker’s page).
Makers tune the lid in different ways. ratproofchickenfeeder.net fits a cabinet-door soft-close cylinder on its small and medium models and a counterweight system on its large one (maker’s site). In the GRIT build, moving the riser arms closer to the hinge makes the lid easier to lift but opens it less, and moving them farther back opens it wider but needs more weight. That trade-off is why a feeder set for heavy hens can fail a light one.
Pros and cons
Treadle feeders give you a covered, high-capacity feeder that rodents and wild birds find harder to use, in exchange for a high price, a training period and moving parts. The claims on both sides come from sellers, so I label them.
What treadle feeders do well
- Lid shuts whenever no hen is on the platform
- Wild birds and some pests find feed harder to reach
- Big capacity: 20 lb to 40 lb means fewer refills
- Rain-ready designs keep feed drier than an open trough
What to weigh against them
- $65 to $240 against $69.95 for a same-size hooded port feeder
- About two weeks of training, longer for timid hens
- Not a rat-proof guarantee from any maker
- Moving parts: owners report latch failures and water getting in
On waste, the evidence splits. ratproofchickenfeeder.net claims many customers save 50 percent on feed once rats and mice are stopped, a vendor report and not a measurement. A keeper in a Facebook backyard poultry group cut their feed bill by about half after adding treadle feeders. Dine-A-Chook, which sells a competing feeder, argues that a treadle box does nothing to stop hens raking feed out, that an open lid lets rain in, and that springs and hinges rust or fatigue (Dine-A-Chook). That is a competitor’s view with no cited data, but it lines up with owner reports of latch failures and water getting in on the RentACoop listing below.
Best treadle chicken feeder picks
For most adult flocks the Grandpa’s Feeder is the best treadle chicken feeder because it publishes activation weights and a training plan, and it states its own limits. The RentACoop 25 lb comes with a rain cover and a lower price, the Rat Proof Chicken Feeder Medium is a U.S.-made option with a soft-close door, and the Feedomatic is sold for chickens and ducks. Prices below were checked 2026-10-09, except the Feedomatic, checked on Amazon 2026-10-20. The full chicken feeder hub has the port and trough options.

Other treadle feeders you will see
Farm-supply sellers stock the Feedomatic card above too. Stromberg’s sells a 26 lb version and calls it weatherproof, but lists different dimensions, 10.1 by 13.8 by 20.8 inches, and the one review on its page reports a unit that arrived dented (Stromberg’s). The Amazon listing rates it 4.2 out of 5 from 578 ratings on Amazon, 2026-10-20 (Amazon listing).
Hatching Time sells a metal plate that mounts at the base of the 26 lb and 44 lb Feed-O-Matic models, which the seller says cuts rodent access to spilled feed at the base (Hatching Time). Treat that as a sign of where treadle feeders leak: at the trough edge and the ground, where hens drop what they rake out. Galvanized treadles from marketplace brands also turn up in shopping results. Check any of those listings for an activation weight before price or capacity, because that is the number that decides whether your lightest hen can eat.
Where to set up a treadle feeder
Put it on a flat, firm base under a roof. A treadle that rocks or tilts binds or fails to close, and a platform sitting in mud gets heavy with muck that changes how it moves. Keep feeders protected from moisture, wild animals and free-flying birds, ideally inside the coop (Utah State Extension). A paving slab under the platform keeps it level and easy to sweep.
Count how many birds can eat at once, not only how many days the hopper lasts. One treadle trough feeds only a few large hens at a time. Add a second feeder for a bigger flock so low-ranking hens are not waiting behind the boss.
Expect hens to stand on the lid and leave droppings there. Do not set the feeder under a roost, and place it where perching on top is awkward.
Leave open space on the side hens approach from, so a bird on the platform is not trapped between the box and a wall, and so a low-ranking hen can get on without being cornered. Place it away from the roost so droppings do not land on the lid or platform.
Choosing Grandpa’s Standard or Large
Choose the size using both capacity and your lightest bird. The seller’s listing gives about 20 lb for Standard and 40 lb for Large. At the University of Kentucky’s intake estimate of 0.25 lb per laying hen per day, ten hens would empty those capacities in about eight or sixteen days. These are planning calculations. Spillage and changing intake shorten them.
The larger hopper comes with a heavier stated trigger. The listing labels Standard’s approximate trigger as 14 oz (500 g), but those units disagree: 500 g is about 17.6 oz. Ask the seller which figure applies to the unit you will receive. Large is listed at about 2 lb (900 g). Do not buy the Large only to refill less often if a light hen cannot operate it by herself.
For a mixed flock, watch the smallest bird eating alone. Following a heavier hen to an open lid does not prove she can open it. If the maker cannot confirm suitable operation, a covered gravity feeder gives light birds access without a weight trigger. The best chicken feeder guide covers that option.
Training your flock, step by step
Grandpa’s seller listing sets out two training stages of about a week each. Follow the instructions supplied with your exact feeder, because training hardware differs between models. Keep feed accessible throughout the changeover and check each bird eating before you advance.
- Set it where hens already eat. Put the feeder in the spot the old one used, at a height that lets every bird reach the platform.
- Stage one, about a week. Secure the lid in its first open position so the flock eats comfortably while getting used to standing on the treadle (Grandpa’s).
- Stage two, about another week. Move to the next position so birds get used to the treadle and lid moving.
- Watch the bottom of the pecking order. Stretch a stage when timid or low-ranking birds need more time.
- Remove the training hardware once every hen eats at the platform. Watch for hens eating from the side of the box, because the lid can swing into their heads when the feeding hen steps off (GRIT).
- Retire the old feeder only after every bird can feed independently. If a hen still cannot open the lid, restore accessible feed and return to the earlier training stage. Do not force learning by withholding food.
A few tricks fit inside those stages. Bolt the lid open through the side holes for the first few days, so hens learn where the feed is before anything moves. Put favorite treats in the trough and call the flock the way you call them for treats. On a homemade feeder, prop the platform up for a couple of days until hens are standing on it. Once training is done, lock the feeder fully shut at night, so rodents cannot work at it while the hens sleep.
If hens refuse, you are not alone. Keepers trade fixes in threads such as Chickens scared of treadle feeder and Chickens hate the feeder style I want.
When a hen will not use the feeder
| What you see | What to check | What to do next |
|---|---|---|
| She steps away when the lid moves | Training stage and sudden lid movement | Return to the previous stage and follow the maker’s instructions |
| She stands on the platform but the lid stays shut | Trigger suitability, level mounting and an obstructed linkage | Offer accessible feed and ask the maker before changing the mechanism |
| She eats only when another hen opens it | Whether she can operate it alone | Keep an alternative feeding point until she can |
| Another hen drives her off | Guarding at the feeding station | Provide another feeding point and observe the low-ranking bird eating |
| She reaches in from beside the box | Access without using the platform | Follow the maker’s side-guard guidance and supervise feeding |
Stop using a feeder if its lid catches birds or its linkage sticks. An owner report about successful training does not establish that your feeder is operating safely.
Bantams and light birds
Your lightest hen sets the limit. A treadle opens only when a bird outweighs its activation weight, so a feeder that works for heavy hens can fail a bantam. Of the makers I checked, only Grandpa’s publishes the numbers, about 14 oz (500 g) for the Standard and about 2 lb (900 g) for the Large, and its page does not mention bantams. If your lightest hen weighs less than 2 lb (900 g), skip the Large.
For any other maker, email and ask for the activation weight in writing. RentACoop’s listing address calls the feeder suitable for bantams, but the page gives no minimum weight, and one reviewer’s bantam Cochin could not open it once the treadle hung lower. Weigh your lightest hen on a kitchen scale, then pick a feeder whose trigger sits well below that number. Keep chicks off treadles; Grandpa’s builds for trained adult birds.
Keeping the treadle working
During feed checks, remove spilled pellets and bedding from around the platform and moving arms. Look for a tilted base, loose fixings, bent parts or a lid that fails to close. Operate the mechanism without a bird present and keep fingers clear of the closing lid.
Empty the hopper before cleaning so old feed does not stay trapped under fresh feed. Follow the maker’s cleaning instructions, dry the feeder fully and refill with dry feed. Inspect corners and seams after wind-driven rain, even if the product carries a weather claim.
Use replacement parts and adjustments approved for the exact model. Changing springs, counterweights or arm positions can change both activation weight and lid movement. Confirm that every bird can still feed after a repair or adjustment.
Building your own
A DIY treadle costs little and teaches you how the lever works. The GRIT build uses edge-glued pine, cedar fence boards and exterior glue for under $20 in lumber. Its author credits it with keeping out songbirds, mice and other rodents, from personal experience rather than testing. Arm position sets how much weight the lid needs, so tune it to your lightest hen.
Homemade treadles hit two problems. First, the lid does not drop shut on its own when a hen steps off. Add weight to the lid, such as a strip of plywood screwed on as a counterweight, until it closes every time. Test it with no bird on the platform before you fill it: a lid that hangs open is just an open feeder. Second, hens scatter feed with their beaks and feet. A small opening in the bottom of the front lets kicked feed fall back in. If squirrels raid your feed, tune the trigger above their weight as well as the rats’. For rat weights to tune against, see the rat-proof chicken feeder guide.
Questions people ask
How long does it take chickens to learn a treadle feeder?
Plan on about two weeks. Grandpa's Feeder trains in two stages of roughly one week each, with the lid held open first and then moved to the next position. Stretch a stage when timid or low-ranking birds need more time. One reviewer on the RentACoop listing removed the training screws after about a week. Some flocks balk, and keepers swap advice in threads like Chickens scared of treadle feeder.
Are treadle feeders worth it?
They are worth it for an adult flock with rats, wild birds or rain at the feeder, because the lid stays shut when no hen is on the platform. They are not worth it if spilled feed is your only problem, since a hooded port feeder costs far less: RentACoop sells a 25 lb port feeder for $69.95 and a 25 lb treadle for $179.95. The best chicken feeders list covers that cheaper route.
Do treadle feeders work for bantams?
Only if the bantam outweighs the activation weight, and most makers do not publish that number. Grandpa's lists about 14 oz (500 g) for the Standard and about 2 lb (900 g) for the Large and does not mention bantams. Weigh your lightest hen and ask the maker for the trigger weight in writing. A bantam Cochin could not open one RentACoop treadle once it hung lower (RentACoop listing).
Do treadle feeders stop rats?
They make feed harder for rats to reach, but no maker guarantees it, and Grandpa's Feeder admits as much on its own page. Adult Norway rats weigh 7 to 18 oz (UC IPM), which overlaps the Standard Grandpa's trigger. The rat-proof feeder guide compares trigger weights against rat weights.
Can ducks use a treadle feeder?
Some sellers market them for ducks. Stromberg's sells the Feedomatic as a chicken and duck treadle feeder, but gives no trigger weight or duck instructions. Grandpa's is for dry feed only, so keep duck water well away from the trough so wet bills do not cake the feed.
Can a treadle feeder stay outside in the rain?
Only if the model is built for it, and even then put it under a roof. RentACoop includes a rain cover, Stromberg's calls the Feedomatic weatherproof, and Grandpa's gives no weatherproof guarantee. Rain reaches the feed whenever the lid is open (Dine-A-Chook), so keep feeders protected from moisture (Utah State Extension).
