The 1st picture is how we found her on Saturday afternoon, I'm not sure who did this to her. She was in their house and the other 3 pullets and 1 cockerel were all out in the pen when I went to let them out to run the yard for a bit before it got dark. The pen is fully enclosed with half inch mesh so we know that it was not a predator. The 'why' is probably a question for the behavior forum, we're still trying to sort out what happened. She had a roughly 1 1/2 - 2 inch diameter ragged hole in the skin on the back of her neck, clearly she was pecked by 1 or more of the others quite aggressively. We separated her, and started by spraying the area with poultry protector 2-3 times a day, and neosporin on her comb which is pretty scabby. The 2nd picture is today. I know it's not real clear but the open wound is gray and dry, there is no smell or redness around the edges. Will the skin close over this eventually? How long should we expect it to take? Is there anything else we should be doing?
