Yeah just checked temps. Average 5 degrees colder in central wi than wny. Doesn’t matter to me what you do with your coop. Just trying to save you some money and space for your birds.Instead of taking advice from people not in wisconsin on insulation of a chicken coop, I would go to the Wisconsin Thread and ask the folks there. Wisconsin cold and the cold other northern states are about 20 degrees apart. I doubt many people realize how much colder things can get once you get west of Lake Michigan. Wisconsin has temps that could freeze some of my southern birds solid.
