I have a new chicken. I raised her as a baby with a rooster, while I had 4 adults. They were raised in a separate pen next to the others, and they shared the yard with them, but the two young ones mostly stayed away from the flock. I had to get rid of the rooster ( due to noise and ordinances) but I kept the hen. Now that she is alone, the flock is picking on her. She still has a separate coop next to the others, and I know they need to establish their pecking order, but they are ganging up on her and pecking at her feet. She has open sores. What can I do to help her socially....and how can I treat her wounds?
