Hi, all! This is our first winter to have chickens. The weather has been unseasonably cold here, but the chickens seem fine. We have two hens and a rooster, and they are all large breeds. Unexpectedly, the chickens began laying yesterday. We had one egg that was frozen and cracked, and another that was cold. Last night I checked the nest box before the birds went to sleep; no eggs. This morning, we had one egg that was frozen and cracked. After I removed it, one of the girls laid another. I'm a little concerned; do the frozen eggs mean that the roost is too cold for the birds? How many times a day should I check for eggs? Any ideas you can give me will be appreciated; thanks!
