We had two of our chickens attack each other today and it led to this: If we hadn't seen him when we did, we know he would have been killed. We cleaned his head up, sprayed Veterycin on him and now have brought him inside the house. At the moment, he is walking around a little bit and drinking water on his own, but I don't know if there's anything else we can do to help him more than what we've done. I don't want to lose him. His feathers were pulled out of his head, we think he has an eye missing and he is very swollen and bloody. The attack came out of nowhere but he was being pecked in the head countless times. Please help if you can.
