Its not my chicken but i saved it from my friends coop while she's away. She is about three months old, tiny red funky looking red with curly feathers. my friend was trying to integrate her into the flock and she has been picked at slowly until her feathers, and skin are completly gone and her skull is fully exposed on the whole top of her head, it looks like there is a small pin sized hole on the top of the skull too. I was just wandering if i should put some kind of dressing on it or something but don't want to do anything that will hurt her, I just feel like she needs some kind of salve and gauze but don't want to make it worse. HELP!!!!
