I noticed tonight that one of my Silkie hens has a large gash on her side. As it goes under her left wing the skin begins to peel off to the point where it is a flap of skin around 1/8" inch thick at the base of the tear. I have already cleaned her sound with hydrogen peroxide and put neosporin on it. She is isolated for the night. Are there any types of medicine I can give her? Also what should I do about the wound? Is there anything else I can do for her?
