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.  Some
customers say that it will stop squirrels too.

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

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 spoils.
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 most 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.

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.

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.
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

Thank you again!

Does it work?
Here are some customer testimonials:

(This 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.

Charles R, Aurora, OR

(Email was edited for brevity)

Just wanted to let you know that after two weeks of use I'm convinced
that your treadle feeder is the best money I've ever spent! It only took
a  few days of training (leaving the door open) for my chickens to
figure  it out.   Obviously the sparrows don't have any more snacks
and  it's a riot watching squirrels try unsuccessfully  to get a snack.

And an update from David a few months later:

It's been about three months since I started using my treadle feeder.
This Has to be the single best thing I've ever purchased for me and
my      chickens! It makes life easier. Since I have an ultra small flock I
only have to fill it once every two weeks.

Keep up the great work!

David H.   
Keep up the skilled work. I love my Chicken feeder and I have had
great  results from your unique design!

just a note to say I love my automatic chicken feeder and will be
ordering  another one soon. what a great value. The chickens were
puzzled by it at  first but now they get it. and it is 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
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 a video of unpacking and
assembling a feeder
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!

but even the wooden ones worked very well.)

This customer ordered his second feeder about a week after
buying the first feeder.   We don't market the rat proof feeder
as squirrel proof but customers say that it will prevent them
from eating the feed:

First of all, I really love your product!

Thanks again for your wonderful product.  I have chicks in the
city and, when I let them out of the coop to pasture, I had every
bird and squirrel in the coop eating the food.  That doesn't
happen anymore!  Thank you!

Construction Details:

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 to allow the lid to hinge properly. The treadle arms
are now bent out of one long piece of ¾ x 1/8 steel bar 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
treadle.  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 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 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 7/16
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.
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 is around 15 pounds with packaging for
the medium rat proof treadle chicken feeder.

Frequently Asked Questions:

Can bantams use the feeder?  
It depends if there are other full size birds in the flock.   Customers
report that their bantams will eat from the side if they can't operate the

The rat proof chicken feeder works only because of two things: the
weight difference between a grown bird and the difference in reach
between a grown bird and a rat.   So the treadle must be set far back and
there must be a two to three pound force used to open the feeder door.
Some tweaking is possible to allow smaller birds to use the feeder but
when you do that you are also making the vermin proof feeder less
effective.     You can gently stretch the spring a bit using two pairs of
pliers to lessen the force that holds the door shut but be careful, you
can't un stretch a spring so do a little and test it, then do some more.

You can order a half weight in place of the full size weight if you email us
in advance AND put that information in the instruction text box when you
fill out the PayPal form.   A counterweight will cost around $10.00 to ship,
almost as much as the feeder, so be sure and let us know in advance
and on the payment form.

You can also order a special bantam treadle that is two inches closer to
the feed door.   The special treadle also has extra counterweight holes
punched so you can move the weight forward to lessen the amount of
force needed to open the feeder.

Just remember that making the feeder easier to open  impacts the rat
resistant features.   Order the bantam modified feeder only if you don't
have a rat colony

Will the Rat Proof Chicken Feeder Defeat Squirrels?
Maybe... Some customers report that it solved their squirrel
problems but one customer reported that her squirrels learned to
cooperate to operate the feeder.

Do you make a large size Ratproof Chicken Feeder?

No, initially we considered making a larger feeder.  However several
things make the idea unfeasible.  First problem is that the feeder
already holds a half sack of feed and when you expand the size to
allow a full sack the increased pressure requires much thicker
gauge sheet metal.  Doubling the span of a beam quadruples the
stress so the thickness must increase tremendously as does the
cost of materials, the cost of shipping the extra weight, and it is so
thick that a regular hand punch won't punch through multiple
layers.   When building the feeder and working on the back edge we
must punch through three layers of side materials and back
materials.    On the top door pivot holes you are punching through
five layers!   We use thicker materials on the inner feed tray and on
the lid on the medium feeder but when we tried using thicker gauge
sheet metal on the sides we found that the assembly was much
more difficult.

If we made a large feeder that would hold a full sack of feed it would
cost over double what a medium feeder sells for which brings us to
the second reason not to make a larger feeder.  The medium feeder
holds 26 pounds of feed, just over a half sack.   Two birds can eat
at  the same time  and a full feeder will hold around 104 day's
rations, or would feed one bird for 104 days, two birds for 52 days,
four birds for 26 days, eight birds for 13 days, or sixteen birds for
6.5 days.   The problem is that customers have told us that each
feeder will only handle around a dozen to sixteen birds before the
competition for the feed early in the morning leads to fighting
amongst the birds.   

You are far better off buying two medium feeders and having twice
the space for the birds to eat at once rather than having one feeder
that holds more feed than is needed.     And that leads to the third
problem that prevents us from making a larger version of the rat
proof feeder, the weight and mass of the door and treadle.    Even
with the counterweight balancing the door and treadle the bird has
to move that mass so making a door that is twice as broad would
open up a can of worms for the design.   A broader treadle would
need thicker steel for the treadle bar, the broader door would need
thicker sheet metal to prevent flexing, the wooden treadle step
would be heavier, and all of that extra weight would require a
heavier counterweight meaning more clearance for the weight as it
would have to be bigger diameter.   

So soon you would have a monstrosity that would cost way more
than twice as much as two medium feeders, you would have feed
stored that the birds couldn't use up in several weeks, and there is
no way that the lighter birds would ever be able to operate a
door/treadle/counterweight system that weighed more than they do.
We finally got home with the chicken feeder and after many worries
about the girls weighing enough to open the door, we installed it
yesterday using only the spring to operate the treadle.

Today both chickens are feeding after a few lessons and the multitude
of sparrows are truly stymied as how to get some of the feed. I have
told a few friends about your feeder and so you might get some more
orders from Bermuda.

Thank-you for this great addition to our little coop.

U.S. and put the feeder in her luggage when she returned to Bermuda.

paperwork so we only ship in the U.S.)
More Testimonials!
Just want you to know, I bought another one back in the
winter.  It has saved me a ton of money in feed, and my
chickens are very comfortable with it, keeps the hen house
much cleaner.

Great design and thanks again.

Do you ship feeders internationally?

Unfortunately, no.  The paperwork is quite a barrier here in the U.S.,
requiring a visit to the local chamber of commerce to get the invoice
certified and the time required to fill out the export paperwork.

However, there are companies set up for accepting a package from a U.S.
shipping company and then forwarding it internationally.

This one charges between $60 and $90.00 to deliver a medium feeder to
Canada or $88.00 to $144.00 to Austraila.

This one offers a wide variety of options and is a bit cheaper than the

If you Google "U.S. package forwarding service" you will find many
companies that will consolidate items and reship to your country.   A
chicken feeder has lots of empty space inside that can be filled with items.
Thank you for the quick delivery of the medium chicken feeder! I was
very happy to assemble and install it before the cold front comes in
tonight. I'm sure our chickens will be much happier this winter with a
constant supply of food--especially when the food is not being carted off
by dozens of mice!

Thanks again.
