I had posted about this back a few months ago and was unable to figure out the problem and I'm not begging/hoping that someone can help me. We have six chicken, four live in one coop and two in another and they share a 5x15 foot run with chicken wire in-between to separate my chicken with severe scissor beak and her bunk mate. The problem is, all four of the chickens housed in one coop are going bald and it's so sad, they look TERRIBLE! Plus the "bunk mate" in the other coop is a polish and has no feathers on her head. This is not a case of pecking or bullying, our "bully" is actually the worse off with no feathers on 1/2 her back and clear down around her tail. Two are missing feathers on almost their entire breast and the other was quite bad, but seems to be better. One also has lost all feathers in her vent area clear down to her legs and leg feathers...it's awful and I feel so badly, I so want to figure this out! Is anyone else having this issue??
