One of my hens is missing some feathers on her back. She has begun to grow in some soft white under feathers but still has a spot on her back that is bare. The other hens sometimes peck at this area although there are no open wounds. The roosters spurs are not yet sharp (as he is still young). The hen is about 8 months old none of my other hens has this problem. Is there some sort of cover or bandage that I can put on her until the feathers come in?
