I have some 2 month old chicks that are in their own pen inside the chicken coop. When I got home today one of them was inside the coop with my adult hens, and her skin is missing from the top of her head to the bottom of her neck. We believe it might have been a chicken hawk that grabbed her and dropped her in the coop. Can't think of any other way her skin could be completely ripped off by about a 2" length. I have her in a box in my garage now by herself. What is the best medicine to use on her to keep out infection while it heals?
