My hard luck pullet Annie. She broke a leg as a youngster, recovered to totally normal, then a few weeks ago had diarrhea and just wasn't doing well for a few days, recovered to totally normal, now I'm seeing her flopped over comb is turning white. She is about 7 months old, had started laying before she got sick, her last egg was on the 10th and she hasn't laid since (unless she's hiding them, but she was laying in the nest boxes). Today the rooster approached her and she squatted, but he didn't breed her, but it's the first interaction I've seen with them since her illness. Her wattles look like a nice shade of red. I've notice the pale comb since she got sick, but the last few days I've noticed that the tips are white now, not just pale. Possible to be frostbite? Or have something to do with whatever ailed her a few weeks ago? (no other chickens got sick, I didn't isolate or treat her) I thought frostbite was black. Hers have not been black at all. Temps have been to 10 F at the coldest, but highs in the 30's to 50's. Coop is ventilated at the top, no drafts where she roosts and no other chickens showing anything like this. She eats, drinks, runs like crazy, is quite wild - I can only catch her at night.
