One of our girls got pecked by two other ones and now she has a HOLE on her back. Her lung is visible in a small portion. She is eating and drinking. We put vitamins from when they were young, so we added that to her water. Going to get broad spectrum oral antibiotic for her water as well. What do I do with the wound? It looks red and healthy, and she doesn't appear to be in pain. She is eating and drinking fine. And, probably happy in the dog cage in the basement since it is 0 outside tonight. Any advice would be appreciated. Why would they do this? These chickens have been together since they were days old, and they have never done anything like this before. Thanks!
