Complete novice here planning on building our coop. I live in SE PA, about 20 miles west of Philadelphia, to give you an idea on climate. I am planning on building the coop elevated, about 18"- 24" above ground and would like to know whether or not to insulate the floor?? While we are on the question of insulation, should I insulate the roof as well?? I know that I will have to provide adequate ventilation, and am planning on windows (cut-outs with hinged covers for now) on all four sides. Just thinking of keeping the cold from coming up through the floor in the winter, and keeping the heat from radiating down into the coop during the summer. Is this unnecessary? Thanks for any and all help! So glad to have such a helpful forum at my fingertips!
