Hello all...well I'll get straight to it. I've got a 9 month old buff orphington who is lethargic and more aggressive than usual. She has refused to come out of her nest box under her own power, and will only eat if she is picked up and sat down next to the food and water dispensers. She eat some and drank a larger than normal amount of water this afternoon. Unfortunately, she is being attacked by some of the other more dominant chickens whenever she goes outside the nest box. Today I put food and water outside and forced all of the chickens outside so she could eat and drink by herself with only one of the other chickens for company. They got along fine. Her comb is collapsed on top of her head, rather than standing straight up as with healthy birds. She also has cracking, dry skin with some scabs on it, although I belive this is because of the extremely cold temperatures we've been having this year (as low as 10 degrees Fahrenheit at night). The floppy comb is unusual though. Also, the comb is pink, rather than the bright red of the others. The feces appears normal. No diarrhea. How worried should I be? At first I thought she was broody, but there are no eggs under her and she hasn't left the nest box in 3 days. None of the other hens appear to be like this. They are all Buff Orphs and Black Austrolorpes. All are 9 months old from the same batch.
