I'm getting ready to build a coop for 7 bantams, with the possibility of adding 2 or 3 more to my flock. I'm thinking about it being 6 feet in length, 8 feet in width, and 6.5 feet in height. I have a general idea of the supplies I need - lumber, nails, screws, chicken wire, and roofing material. I'm wondering if anyone knows what size wood worked best for the frame of the pen as well as for the coop. I have absolutely no carpentry experience, however I do have a couple of friends ,who have woodworked for a multitude of years, helping me build this. Also, does anyone know anything about spray insulation, and if it is chicken safe? I was thinking about using it to insulate the coop. Thanks.
