This is my first chicken winter and believe me, I read everything I could get my hands on about keeping chickens in the winter (cold climates). Chickens are pretty resilient in the cold. As long as they have good shelter and are fed well, it seems they do just fine. It can get pretty cold here in SW MO in the winter. It has been pretty mild this year though. We did have some pretty cold nights and days though and I worried about them sooo much.
Lost a lot of sleep some nights, really for nothing, because next mornings they were all up bright and early and as chipper as can be waiting for me to let them out of the coop. My girls (and boys) couldn't care less how bad the weather is! Even the most crummy dreary days...they want to be outside, going back into the coop only to lay their eggs for me!
I still worry, and I suspect they will get through the winter better than I will!
Your girls are beautiful....great pics!!!
