I have my design for the coop ready, but I am still debating the materials we are going to use. It will be a frame 4x4x4, with t1-11 walls. No insualtion. So ~ do I need insulation. I'm in NJ and there will be 5 hens in there. If I ever needed to hang a heat lamp in there, is it okay with the t1-11. My step father was wondering if the t1-11 gives off a smell if it warms that would be harmful to the chickens. I'm thinking no, if ever did then it's TOO warm. Do I need to hang regular plywood first and the t1-11 over that, or is the t1-11 alone okay?? That's it for now, but I'm sure I'll have more questions once construction begins this weekend. Wish me luck !
