We had 2 chickens and one was killed by a dog. Not wanting the remaining chicken to be lonely we got her a new friend. She has been bullying the new chicken and pecking her. I tried using vicks as people had recommend on the new chicken but its not worked. New chicken has a wound on her neck, not too deep but I am concerned. I have cleaned it with betadine and there was no blood. Does she need to see a vet? She wont come out of the bedroom part of her coop. I have seperated them now. Will they always fight? This is the first time i have had chickens and I don't know what to do. They are pets and i don't want to lose another one any advice will be appreciated.
