About a week ago I chased a hawk off one of my hens. It had ripped off skin and feathers along one side of her head. I have her in the house and have been nursing her back to health. I didn't touch the wound until 2 days ago other than to squeeze some neosporin on it. Since then I have put hot packs on it followed by hydrogen peroxide and it looks clean and healing. The problem is she has stopped eating yesterday and today. Before this she nibbled at some fine grained chicken feed. I can get her to drink a few sips of water through the day. Any suggestions about getting her to eat?
