We haven't had a lot of snow lately, but we have had some unbelievably frigid temperatures! In the almost five years that we've lived in Colorado, this is the first time we've experienced temps so extremely cold and miserable. When faced with such arctic weather, we worry about the hens. They have a heat lamp in the coop that is connected to a timer, which Neal set to come on every two hours for 15 minutes at a time. He also connected a dual thermometer gadget with one piece in the coop and the other in the house so we can gauge the temperature of the coop. Most nights the girls were staying pretty warm, but there were some nights when the heat lamp just couldn't keep up. And with only three hens, they were limited in how much body heat they could produce on their own.
