Well, I'm almost done with the coop. If you check out my page you can see it framed out. The only problem is now that I put up the 1/2" plywood and enclosed it, not everything is square. There are "cracks" around the windows and around the exterior nesting boxes. I was going to use some 1/4 round trim to block the majority of the draft that would come in during our harsh NH winters. Should I also use some of that expanding foam to seal it up tight? Also, how does one go about making ventilation in the soffits (?). I'm obviously not a builder by nature...............Help please, the biddies need to go out asap!
