One of our barred rocks injured her foot. We separated her so she could heal because the other chickens were beating up on her. She is all healed now and we are trying to introduce her back to the flock. we left them free range in the backyard one day and when we came back her come was all bloody as the other chickens appeared to have been picking on her all day. Is there anyway I can get the other chickens to stop pecking at her and picking on her all the time as she appears to be at the bottom of the pecking order now. In the evening if we go outdide she will jump up on us to try to come into the garage. My hens are about 4 to 5 years old.
