I had two chickens- a Delaware and a Barred Rock, both about four months old, and the Delaware died. I didn't want my Barred Rock to be lonely, so I got two baby chicks- a Silver Laced Wyandotte and an Australorp. I introduced them, for the first few weeks through a fence. When the baby chicks were about two and a half weeks old, I let them free with close supervision. Occasionally one of the little chicks would come up to my Barred Rock, and she would peck at them. Then I separated them for a while and reintroduced them. But one afternoon my Barred Rock started to flap and go crazy inside of her coop where we can't see her. When I checked on her, she had red along the the top of her beak to a little into her comb. The next day she twitched while she walked. I fear that she might be lonely, or is just going crazy. I don't know how to help her and I am concerned for her health. Please help, BYC professionals!
