One of my buff Orphington's started to molt - at least I think that's what was happening -about six months ago. She has still not grown her feathers back. For a while there she was staggering around but that seems to have subsided. She's definitely in pain if you try to pick her up and she likes to stay off by herself for the most part. Can anybody tell me what's going on? We always thought it was just a bad hard molt but she hasn't regrown her feathers. We have four other chickens and they are very healthy and happy.
