When I came home from work today I noticed my 2 year old chantecler hen sitting outside by the chicken door. She is usually one of the first to come inspect the treats. I checked on her and when I picked her up, her feet were nearly frozen solid! I immediatley put her in the coop and closed the chicken door to keep all of them in. There is some movement in one of her feet. She seems to be getting around on her own and is eating and drinking. I put her under the heat lamp. my questions are 1) can her feet be saved? If so what do I do? 2) Why wouldn't she come in the coop? Why would she stay outside to the point her feet froze?! All the other chickens are fine, none of them seem to have any frost bite on combs or waddles and are doing just fine.
