So I have six hens and while I was out of town cane home to one of them having a patch of feathers missing on her back close to her tail. So I separated her as the skin was very lightly bleeding in a couple spots. I kept her away for a few days and put her back in yesterday. The other hens ganged up on her and in fact they started flying, claes and all. She avoided them for the day in the run and a couple minor spats. This morning that same spot looked like an abrasion and she was limping a bit so I have taken her out again,cleaned her wound and she is now not with the rest of the flock. Once it heals I object to put her back in and want to avoid the combat. I don't know why all of sudden she is the target or what I should do after she heals?
