Nice to hear about those Alaskan winters and chickens OK. We had an early cold snap here with record dump of 3 feet of snow...of course I wasn't ready for it. The chickens were fine, I picked one out of a snow bank who was apparently sleeping and thought I was rude to do that....I wanted to check her body heat...she was fine, and a little concerned about predators until I realized they can't move in this stuff either. First snow many of them have seen and they learned to walk on top of it, until they figured out flying was easier. It was only down in the 30° and 20° at night. No problem. Some did shiver a bit inside but did OK. Since, I have windproofed 3 sides of the coop, and added a tarp over the pop door with straw instead of hard dirt to stand on. Last year I had chickens roosting on top of the coop in the middle of a blizzard with snow drifted around them. They could go inside if they wanted. Through the storms, the chickens don't eat or drink much, they seem to just hunker down and sleep....i can tell when its over because they wake up. Of course though, my chickens come from a long line of free range chickens that really had no coop, and it doesn't get cold here like Alaska...brrrrrrr! But i would think if you live there you'd want a hardy chicken that can adapt to those temps....what better way to find out? If you heat the coop they'll never adapt. But then....are there wild chickens in Alaska? What type of fowl live there year round? Visiting Alaska is on my bucket list.
