This is the enclosure that I made by stapling1/2" hardware cloth on 3 sides. I buried 1/4" hardware cloth around the bottom about 10", then added small patio stones to make sure the chickens didn't dig too close to the buried screen. The front was framed by my handy spouse, and I actually made the door. The ceiling is just the 1" chicken wire to keep out the cats. So far it's been safe and sound. The small coop is ok for 3 seasons, but not insulated or warm enough for the very cold winter.
