I got a coop started. I need to put some roofing on it and paint it since the exterior is OSB. I still want to add another 2 nest box on one side. I have 3 nest boxes on the backside. I need to cut a door on the other side large enough for us to keep it clean. I put a rubber mat in the bottom that I can pull out and spray off. I also need to get some roosting spots in it. I bought a 1" PVC pipe for that. I built it 6'x3'. It is 2' off the ground and the roof is 6 ft high with a 6" drop for the 3' depth. I attached it to the pen. I need to enlarge the pen for a run. I have 11 Rhode Island Reds in that unit. I figure if I add 2 more nest to make 5 nests and make the pen larger it will be fine. I have been letting them out a a couple hours to free range in my yard. They are doing a lot of scratching and digging. I get a kick out of watching 1 bird find a worm or bug and watching the rest chase it.
