Hi when i lived in alaska we had chickens the best thing we did was bought a small Metal shed for wintering the flock and adding 2x4 for embracing the snow heat lamps x2 and we also had food and water fed daily as we did have some ice on both. until we got smart and put them closer to the light . for covering we used some hay but worried about the heat lamps this was in the 70's
the 8ft by 8 ft building worked great and my rabbits in there helped too. Good luck Tammy
