I'm south of you in Western PA so it's gets cold here as well. I've heard from different people that as long as you keep them from getting wet they should be okay during the winter. I mean if you really think about it with wild turkeys they don't have much shelter during the winter and they seem to do fine.We're in Maine, so I've been looking for a larger chicken coop with a big pop door. It gets 20 below during the winter, but maybe I'm being too careful. Of course, he is alone - so, no other turkeys to snuggle with just yet. Thank you for sharing the logic.
