My cockeral is having some trouble with one of his wings. I can't figure it out for the life of me. Today he went in the hen house and came out a few minutes later with a sagging wing. That is the best way I can describe it. It is not sitting in the same location as the other one. He keeps flapping it and even walking backwards while flapping it. I don't know if he did something with location or what. Has anyone ever run into something like this before? Maybe he fell of his roost while he was in the hen house???
