Peepinator---I have a feeling this is something chronic that comes out when the birds are stressed...I have another one who had this problem right after I got her, although not as severe, who recovered after a few days on antibiotics. The one that has it now had to be separated from the other birds and put into a holding pen inside the coop because she kept fighting with the rooster and had a bloody bare spot on her neck that I was worried would send the other birds into a pecking frenzy. She could still see the birds, and they all cuddled up together next to the wire at night, but she was obviously very upset about being in the pen None of the other birds are showing any symptoms, but I'm treating them all anyway. I brought her in last night when I found her and put her in a warm, dark room in a carrier with a heating disk. I opened the door this afternoon so she could get out if she wanted to, but she doesn't seem to want to come out. Or she's too weak, maybe. She layed an egg sometime this afternoon, poor thing. But yes, she's away from the other birds. So sorry about your hens---hope none of your other birds get sick!
