I went out to the coop this evening and found one of my hens dead on the floor by the door! She's about 11 months old. Up until now, I haven't noticed anything strange about her or the others at all. There was no blood on her body anywhere or any sign of an attack. Could she have frozen to death? It's 20 degrees here right now, but I have a heat lamp in on in the coop. The others seem to be fine. My husband said when he went out last night to give them water, one of the hens was in a nesting box making funny noises. He's not very chicken savvy, and he thought she was trying to lay an egg, but he's not sure. He doesn't remember which hen it was. So, it might have been her. Can chickens die from being eggbound? Could that have been it? She laid distinct brown eggs with dark speckles, and I hadn't seen any for the past two days, but that was not unusual for her at all. The only two odd things I noticed about her body was that there was some mushed food in her mouth and her comb had tiny whitish areas on it. But, I didn't know if that had to do with her laying right next to the door and it had started to freeze. Could she have choked? Do chickens do that? I'm really bummed about this.
