You know we are humans & care for our animals. It gets cold outside & human instinct kicks in.Gosh, I hope my pets are safe first reaction. Heck, I live in Texas but when the temp drops I'm worried about my animals. I couldn't imagine living in Alaska I'd have a heart attack worrying about the girls. We're humans with no down feathers. We get cold . Animals, also get cold but they live outside 24/7 so they can adapt. Its nature they grow thicker hides for bad winters more feathers etc. I hope for all our chickens this winter.
