Well I am not quite sure what happened to one of our hens, although there are definitely hawks in the area, but she has a very bloody area on her back. I haven't probed to see how deep, as it looks pretty painful and bloody-though not gushing. My husband noted it first and when i went to check on her she was in one of the coop's laying boxes ? maybe laying. Do I attempt to clean it and put antibiotics on it? Isolate her so she doesn't get pecked at? We have placed over our run string that runs vertical and horizontal to dissuade any hawks from coming in, but maybe some determined and hungry hawk made it....we'll have to reassess. Any comments or suggestions for the hurting hen would be appreciated!!!
