I have a new hen that I had to separate because she got picked on in the crate while bringing her home. After she healed up I slipped her into the coop and the next day when I checked on her, a good chunk of her top feathers on her left wing were sheared right off. It made her a little off balance but I left her in the coop. The next day her flight feathers were sheared off on the same wing. So now she is so off balance, she can't fly or do anything! The only thing I can think of is that it was the rooster. He hasn't done this to anyone else (he is new to me and our first rooster). I just took her out of the coop and put her in my garage in a pen. I don't think there is anything I can do though until she molts right? Is should happen this fall.
