I am building a coop for silkies. it is 5'x5' approx. I have ventalation along the top under roof overhang. I am a bit undecided on wall/windows I have a boat load of used roofing tin and used lumber. I can cover the coop with a combination of either I also have windows from an old house I can use I can make entire walls windows I also have a ton of 1/2 inch wire mesh the walls are 5' wide and 3.5 tall Top few inches around the coop will be wire for ventalation. I am just really confused how I sould enclose the coop. I also have 3 8x4 1 inch styro insulation boards to insulate. I live in tenn so warm summers 90-100 many days and winter temps get down to low teens some single didgets. Please help how should I enclose this.
