The coop I'm building is coop #1 in Art of the Chicken Coop. It'll be 4' X 5' and the run will be about 12' X 6'. Got the ground ready today, its a gravel RV parking area, so racoons won't be able to dig under. There is a 4' X 4' covered structure that used to be a playhouse that I'm using as a corner of the run.
