I have a young chook that is pecking herself really badly. She has a huge bare patch on her back that is red raw looking. I know she is not being pecked by other chooks as she sleeps in a separate cage with only one other chook (a very gentle Frizzle who I am sure is not doing it) and they all free range during the day. Plus I have seen her do it. How can I stop her doing this? Is it worth wrapping a bandage around her over the injured area?
