I have a hen that had some feathers missing on her back. It was nothing bad, but her skin was exposed. My rooster mounted her, and cut her skin with his spur. There is about a 2 inch by 3 inch part of her skin has peeled away and bunched up exposing her muscles. It looks like she was skinned, literally. It is not bleeding or anything. I have separated her so no one can mount her again and no one can pick at it. Is there anything I can do for her to help this heal? I realize she will not be able to regrow feathers in this area since there is no skin left. Does she have a chance at this healing OK? Please help.
