Hi, everyone. I'm new to the site. This is my first winter with chickens and, based on what locals have told me, my 3 girls have an unheated coop. But we will get to -22 tonight--our coldest night this year--and now I'm worried that they will be too cold. The two windward sides have hay bales below them and are wrapped in plastic, so there are no drafts. There is 6" of pine shavings on the floor and they have heated water. So my fingers are crossed that I'll still have a reason to be back on the site tomorrow.
