Are you worried about bird flu or Avian flus spread
by wild birds?  With the outbreak of Bird Flu in early
2015 it is very important to prevent wild birds from
sharing feed and water with your flock.  Authorities
in several states have already begun testing and
euthanizing  backyard chicken flocks and it is
reported that they will test flocks up to seven miles
from any outbreak.  .

My own feed bill plummeted by 75% after I began
using the prototype treadle chicken feeder.  Mice,
rats,and wild birds 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.   The door is also spring loaded  to
keep the door tightly closed and to prevent rats from
pushing the door open, something that no other
inward swinging feeder on the market can prevent.
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
at that time the cost was outrageous at $200.00 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
vermin 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.

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 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.

Why Buy this Feeder?

  • It is going to save you a lot of money on feed
    costs by keeping the rats, mice,  and wild birds
    out of your feed.  Some users report that it also
    defeats squirrels.   Many customers report a 50%
    savings in feed use.
Above is a photo of a commercial organic free range
chicken operation that researched every chicken feeder in
existence before choosing our feeders.   

For five years they had a real wild bird problem that was
eating an estimated 20 pounds of expensive organic
chicken feed per day and the free food encouraged
massive flocks of birds to hang around,destroying their
organic lettuce crops as well.
We started out making the feeders in the U.S. at my
cabinet shop in Oklahoma City but two things happened;
the feeder became more and more complicated and
costlier to build which meant there was nearly no profit in
making the feeders and we found that it was difficult to
keep up with demand. Many a night feeders parts were
taken home to be assembled on the kitchen table so they
could be shipped the next day but starting in 2013  we
began working on our new shop in the Philippines on the
old Clark Air Force Base.  They call Clark "Little America"
because it looks exactly like a small town in the U.S.

It took two years but the first container load of feeders
arrived in early February of 2015 and we have been able
to afford to increase the thickness of the galvanized sheet
metal throughout the feeder, add additional safety seams
on the lid and inner feed tray,leaving only the front side
edges un-seamed in order to get a good tight fit. Those
edge are factory edges though and perfectly smooth and
they have been de burred by hand.

The shop is 100% owned by my company, managed by an
American family, and staffed with hard working Filipinos
who are extremely grateful to find well paying full time
work with benefits, a rarity in the Philippines.   Some
workers were from the Visayan region and were displaced
by the 2013 Bohol earthquakes which was followed by
Typhoon Haiyan/Yolanda which wiped out sections of
Leyte including Tacloban, killing over 6,000 people.  The
workers do an outstanding job building the feeders and as
they work on the product full time the feeder they are
producing is actually better quality than the ones we were
building in Oklahoma!
What does 1,300 Rat Proof
chicken feeders look like?

Here is a picture of the first
container load of feeders
that arrived from our
Philippines branch in
February of 2015
A container  of feeders should have meant that we weren't
assembling feeders at the kitchen table any more but we
actually ran out in December of 2015 and had to produce
them in Oklahoma City again for about a month before our
next container arrived!  The quality is better than what we
were producing in the U.S. and finally  making a small
profit on the feeders

We un-box each feeder for a quality inspection before
shipping to our customers.   We are still committed to
recycling or diverting waste wood from landfills so we
bring the feeders in missing the hardwood treadle step
and softwood spacer block which are produced from
hardwood scraps  and  surplus pallets from material
Why is it so important to keep rats and wild birds away
from the chicken feed?

Two words:   Bird Flu

In early 2015 health officials in a half dozen states
including Washington, Oregon, Mississippi, Minnesota,
Arkansas, and Kansas to name just a few, have found
backyard chicken flocks that were infected with bird flu.  
Some authorities initially blamed wild ducks until it was
pointed out that the infection hot spots were reported in
reverse of the normal migratory patterns and that up North
the wild ducks have yet to show up due to cold weather.

A more likely culprit are small birds like sparrows or
starlings spreading the disease agents on their feet or
passing the disease during the incubation period before
they get too sick to fly.  Some species of wild bird are
immune to the disease but are a carrier.
Stop the wild birds from spreading Bird Flu before city,
state,and federal officials  use this as an excuse to ban
backyard chickens!  

We know how hard many of you fought to get permission
for backyard flocks and how many are still trying to
convince city officials to allow backyard birds.

A customer testimonial:

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.

Once you stop feeding the wild birds and rats they will
move elsewhere and take their droppings and ancillary
damage with them.   One commercial flock was losing their
small greens and lettuce crops because of the wild birds
that were attracted to their free range flock but the
purchase of the rat proof feeders eliminated the food
source and they could once again sell the small greens and
lettuce at the farmers market because it wasn't pecked by
the wild birds.

If you are in the city you won't have neighbors complaining
about the rats that are attracted to your coop.    One more
reason that the City Council might allow citizens to raise
chickens in backyards.

Birds train quickly with our style of feeder, the door swings
away from their head, not over their head so they are less
afraid.  The door will push a bird's head out of the way
instead of trapping the bird.  The Grandpa feeder had such
a problem with birds getting trapped that they had to add
side guards.  The birds don't have to reach deep inside the
feeder to eat like some of the competing brands so the
feeder will work on medium and large birds too.

It is solidly made and it actually will defeat rats, wild birds,
and some  customers say squirrels.   There is a gorgeous
new feeder on the market, just pretty and neat  as all get
out but it has a plastic lid and a plastic treadle.   Not only
that, but the treadle is huge and will allow rats and wild
birds to defeat the feeder!  Plastic degrades in sunlight,
rats easily chew through plastic, and using plastic saves
money but spending a few dollars more on sheet metal will
make a feeder last for  years.
  • The medium feeder will feed a single hen around
    100 days or ten hens for 10 days.   You can go on
    vacation and not worry about the birds running
    out of feed.
  • Your flock will be healthier once the vermin stop
    eating out of the feeder and bringing their
    diseases and parasites along with them.  
    Commercial flocks know this and they go to
    great lengths to keep vermin out of their flocks.
The owners had this to say about their Carpenter Shop Rat
Proof feeders:

"Fifth Crow Farm now has brand new, treadle chicken
feeders! … and they’re working!!!     When a chicken steps
on a lever at the front of the feeder, the feeder opens and
they can eat.  When they step off, the feeder shuts.  A small
bird like a starling can’t get it to open, while a plump hen has
no problem with it.    We’ve created units of 6 small feeders
mounted to weather treated plywood which is affixed to a
pallet so they can be moved with a tractor."
