I've read many conflicting opinions. I'm planning on putting some kind of paneling on the inside of the coop, to keep them away from the nails, etc. Just to make it nicer inside, too. I've found some vinyl panels at Home Desperate that are light in color, weight, and look like they'll be sturdy enough. Is the dead air space between the outside 1/2" plywood walls and the paneling enough insulation? I've read about moisture problems, etc. and thought if the wind were blocked it would be enough. It gets cold here, in gardening zone 6a, what do you all think? If you think insulation is important, then what should I use, the pink stuff or some kind of board? And then there's the peak of the roof, do I close it off or insulate all the way up (hubby says there will be moisture problems if we don't close off the peak).
