In one of the coop designs on this site I saw feeders inside a coop that were mounted to the wall. They appeared to be made out of PVC pipe. The person did not give detail on how they were made just that they worked well and the hens didn't waste the feed. can someone please help because I would like to use them in my coop. thanks Mother of 3 kids (11, 8 and 4) one dog, one cat, 3 RIR 8 weeks old and 2 GLW about 9 weeks old. New to this chicken thing and loving it. Love this site very informable.
