Are you tired of feeding more critters than chickens?

Are your feed costs out of control?

This treadle chicken feeder will prevent  small wild birds, mice, and rats
from stealing your expensive feed and prevent  the spreading of disease
and filth.  

Raising chickens inside city limits requires being a good neighbor that
prevents rats and mice from colonizing the area.  

My feed bill plummeted by 75% after I began using the prototype treadle
chicken feederfeeder.

Mice and rats not only eat feed out of regular feeders, they fill their
cheeks with extra food and store it in their burrows.

The treadle feeder design is narrow and distant to prevent heavy rats
from operating the treadle and reaching the feed. The rat would have to
weigh over one pound to work the treadle feeder and the treadle is set
so far back that and when the rat leans forward to get to the feed the
leverage is less and the door closes.   We recently added a spring
loaded door system to keep the door tightly closed.

If you already have a large rat colony living under your chicken coop, it
has been reported that rats will initially learn to swarm the treadle feeder
but eventually the ones sitting on the far end of the treadle figure out it
doesn't pay to be there and the cooperation ends. I guess rats are like
politicians, the heist always falls through as they squabble over the
On the left, a picture of the lid of rat proof treadle chicken
feeder open showing inside the feed hopper.  

The right picture shows the door open so you can see the
feed tray below.  The narrow lip on the front prevents
chickens from raking feed out when they eat.

There is a small,  narrow, wedge shaped gap between the
sides of the door and the front flanges which is required
due to the door design but mice, rats, or other vermin can't
get inside due to the slickness of the galvanized metal.  
They can't climb the slick metal feeder to get to the gap.  
The bottom of the door closes tightly but the door design
requires a space to operate properly preventing us from
eliminating the narrow gap.

The feeder is assembled using pop rivets, screws, and
bolts, no spot welding to break a few years down the road.
When I started raising my own back yard flock the rats became a serious problem. I found the wonderful metal  Grandpa treadle
feeders online but the cost was outrageous at $150.00 and up and they could trap a chicken's heads due to the design. I couldn't see
paying that so I started making prototypes. I found from testing the prototypes in my own chicken house that was over run with
mice and very large rats that mice and rats will starve out in about two weeks once the rat proof treadle chicken feeder was installed.
The starving rats started ranging into the open yard during the day to look for food and my two dogs killed many of them.
Medium Rodent Resistant Chicken Feeder
$65.00 + shipping
The medium rat proof treadle chicken feeder hopper holds 26 pounds of  
laying pellets or other feed, and has a 100% galvanized sheet metal
feed  tray and hopper so the feed flows easily and sanitation is assured.

Generally a laying hen eats around 4 ounces of feed per day, so one
pound of feed should feed four birds one day, 7 pounds per week per
four birds, or 3 1/2 weeks per full hopper of feed for a four hen flock.

Approximate assembled size is 18" deep x 14" wide x 19" tall. Shipping
weight around 15 pounds  with packaging for the medium rat proof
treadle chicken feeder.
Small Rodent Resistant Chicken Feeder
$60.00 + shipping
The small metal rat proof treadle chicken feederis the same
height and depth as the medium rat proof treadle chicken feeder
but the width is 7" instead of 11". It holds around 12 # of laying
pellets and weighs around 12# packed for shipping. The small
rat   proof treadle chicken feeder is perfect for smaller  coops and
costs $60 plus shipping.

The small rat proof treadle chicken feeder should feed four birds
for twelve days, just under two weeks.  

The approximate assembled size is 18" deep x 10" wide x 19" tall.
The vermin proof chicken feeder was designed using feedback from chicken owners on the forum at The treadle  
feeder evolved through several versions from a plywood feeder to a very solid galvanized automatic  metal feeder thanks to the feedback
from the forum members.

The vermin proof chicken feeder is constructed of light weight 30 gauge and 26 gauge galvanized steel construction with steel treadle arms
for reliable operation under harsh conditions.  The latest version of the mouse proof chicken feeder has a vastly improved lid hinge system
that uses a galvanized wire axle to allow the lid to hinge properly. The treadle arms are now bent out of one long piece of 3/4" x 1/8" steel to
make it stiffer and more durable, replacing an assembly that consisted of a left and a right treadle arm and a wooden treadle step. A narrow
hardwood step gives the chicken a comfortable "perch" while limiting the ability of a rat to reach the feed if it is heavy enough to operate the

The front swinging door  on the mouse proof chicken feeder has also been redesigned using a heavy steel axle assembly that is gas
welded together using bronze brazing rod. The new door hinging system employs  an integrated 1/4" crank rod that should last for decades.
Replacement parts will always be available should the need arise.  

The mouse proof chicken feeder is assembled, adjusted, and tested, then disassembled for packing.  Reducing the size of the box by
removing the treadle cuts around 30% off the shipping costs.  There are instructions on how to put the treadle back on, about a five minute
operation if you are a klutz.   The wire crank rod does need to be bent under to secure it so a pair of pliers is needed and a 3/8" wrench to
tighten the nylon locking nuts.

If you have deep litter in your coop you might want to set the treadle around two to three inches off the top of the litter by hanging the rodent
proof chicken feeder on the coop wall. The birds will hop right on the treadle just like it was a roost pole.   The rat proof treadle chicken
feeder should be attached to a larger base or fastened to the coop wall to prevent tipping when empty. A wooden mounting block is
included with the feeder to hang it from a wall or fasten it to a larger base.

Training your birds is very easy and quick IF you remove all
other feed sources from the coop.

The hens learned very quickly that stepping on the treadle
meant that they got to eat! If they don't pick it up in five minutes,
wait a few hours till they are hungry then trip the treadle a few
times so that they see the food. That earlier model had a
counterweight that moved up and down, quite noisy. It was
replaced with a fixed counterweight set at around one pound.

The rooster however was a little slow in picking up the idea to
step on the treadle for his dinner. He eventually learned the trick
though. He certainly let down his gender...

If you need a vermin proof chicken feeder for use outdoors, you
can construct a rain shed out of corrugated plastic or metal.
See the pictures below for an example. All you need is
something that will keep the blowing rain from hitting the door
and dripping down into the feed tray. Making it deeper would be
better if you have the room in your chicken pen. The feeder itself
is watertight to rain falling straight down due to the lid.
Below are a few of the many testimonials from our

Got the rat proof treadle chicken feeder and have been using it a few weeks
now and wanted to give you some feed-back:

First off, it works great. I looked all over the web for an affordable treadle feeder
and yours is pretty much the best for the price. I also bought a wooden treadle
feeder from my local farm-supply shop, just to check it out, because it was
cheap and a different design, and basically, it sucks. It is the style where the lid
lifts up instead of back like yours does, and it hits the chickens in the face when
they step on the lever, they get scared, and step off, and don't come back. I had
that one in the coop for over a week and the chooks never learned to use it. I
had to prop it open for them to get fed. Yours, they learned to use on their own in
just a few days. Great design!

Thanks again for making an awesome feeder. I am going to take the one i
bought from my local farm-supply shop back and try to convince them they
should be ordering your feeder instead.

My husband put together the rat proof treadle chicken feeder today...he
complimented you by saying..humm...pretty smart guy...  nice design...

I LOVE THEM!   I can't wait to order the next 4 automatic chicken feeders.

They were lighter than I expected, installed easily, and by this morning the
chickens are sitting on treadle to eat with the door propped open. The
turkeys are tall enough to just reach around and eat. We'll see how they
do when it is no longer propped open.

Below is a close up picture of the new spring loaded
door.  Older model mouse proof chicken feeders can be
retrofitted if they have the steel axle/crank coming out of one
side of the feeder, usually the right side.   The spring keeps the
door closed completely and provides resistance to any critter
trying to push its way into the mouse proof chicken feeder.
I would like to order a second rat proof treadle chicken feeder! My
chickens are getting used to the first one and it seems there isn't
quite enough room for them all to eat in peace. So just to let you
know I will send the same amount I did a couple of weeks ago!

Thank you again!

Does it work?  Here are two recent emails from customers ordering a second feeder.  The first customer had one of the original
rat proof treadle chicken feeder with the three piece treadle assembly which we have upgraded to a one piece assembly and it
was needing an occasional tightening due to heavy use.  We gave him a discount to upgrade to the new feeder:

Hi Al
I’ve been meaning to email you for quite some time. I ordered a medium  rat proof treadle chicken feeder last October and it has
been  a  
god send. You have an amazing product that has significantly decreased (if not eliminated) the rats around our coop!   I
have been experiencing one small issue though which has perhaps been fixed with your new design.  All that to say – I’m  
excited to see the new design! I see that the new pedestal is composed primarily of one solid piece of metal, which I assume can
only help to improve the integrity of its function.

just a note to say I love my automatic chicken feeder and will be ordering another one soon.

sooooo well made. thank you!

I purchased the small feeder for my 6 chickens. They learned to use it within 2 days and my feed bill was reduced by 90 %.
Chickens are happy, I am happy, this is a wonderful product. I am purchasing another feeder for a friend of mine.
Susan K., Phoenix Az.

A 90% savings in feed will pay for a rat proof chicken feeder in just a few months not to mention the lesser chances of diseases caused by
rats and mice eating the same food and drinking the same water as the chickens.  Fleas and lice are also spread by vermin and fleas are
the main disease spreading factor of bubonic plague!    Rat urine is responsible for the spread of leptospirosis, which can result in liver and
kidney damage in humans. It  can also be contracted through handling or inhalation of scat. Complications include renal and liver failure, as
well as cardiovascular problems

More Customer comments on the feeders:

It's fantastic!  We had a similar set up made of wood, but the rats obviously chewed into it and
were going through the food.  My husband feeds the wild turkeys we have, and rather than
having to run  outside each time he sees them, he wants to leave a feeder out for them,
too! :-)  Thank you very much!

Videos of the feeders in use and unpacking an assembling the feeders
I just installed the rat-proof feeder from The Carpenter's Shop in Oklahoma City. It was delivered quickly, it's well-made, and
some of the chickens have already jumped on the lever to open the grain door. So far, so good for adult chickens. There's
just one thing--I can't get them to stop looking at their reflections in the sheet metal. Oh, those vain chickens!

steel ones.    The top picture it is in the
coup and the bottom one I blew up so you
can see it better.  Thanks Kristi H.

(note that this is one of the original
wooden feeders and has been in use for
several years sitting out under a shed
roof.  The galvanized feeders will do even
better but even the wooden ones worked
very well.)

This is a second unit -- I am getting this for my
neighbor as a gift. Your feeder works very well -- very
easy to pay for itself. Also, I "seeded" the feeder with
meal-worms to help train my hens to begin using it.
