So I'm curious- I have a coop that was modified from a Ferarri windshield box. It is about 6X3X3. We have the front off for access from the flock with the food and water hanging at the front. The have about 14 RSL's and are almost all laying now. Their pen is about 14X14 fenced with bird netting over it. I want to winterize the area for them. We live in western NC and get about 3-6 good snows per year but it will be probably 25-40 degrees for about 6 months. I'm concerned that the chickens will freeze. Am I being overprotective? We were thinking of getting a heat lamp for one side of the coop but dont want to overheat them...I also need a good way to seal the front - there is some ventilation at the top on both sides at the roof. I want to be able to keep the wind out and the heat in but not have it permanently sealed as we will open it back up this spring. Any thoughts?
