Hello! I am new to the site and new to chickens as well, but I am in desperate need of help. A few weeks ago I noted that my Delaware was staying away from all the other chickens (4 total). I was told to make sure she wasn't sick and sure enough when I checked her out she had a hole in her head. I had no idea how it happened. I decided to spend some time observing the chickens behavior and realized she was avoiding one chicken in particular. I came to the conclusion that the Delaware is at the bottom of the pecking order and that the other chicken was bullying her. The coop is big for only four chickens however they are only on wood with shavings. I am currently in the works on expanding the coop so they can go out and peck at the dirt to entertain themselves a little more. In order to heal the wound found on the Delaware I separated them. Sure enough she is in good health now. The spot scabbed over and new feathers are growing. However, the Delaware is completely miserable all alone. I am now trying to reintegrate the Delaware. I was instructed to get a solution to put on to make sure she doesn't keep getting pecked on the head. I put it on before reintroducing her and find out that the solution is purple. The moment I put her in the coop the other chickens come over and start pecking the purple spot (quite viscously). I am not sure if they were pecking because it was purple or just picking on her. Please help! I don't know what to do. I want my flock back together. Do I need the separate the bully chicken to put her in her place? I am expecting an egg from the bully chicken any day now and I really don't want to interrupt that process due to stress and it makes me so sad to hear the Delaware calling out for friends constantly. Any advice is greatly appreciated.
