I have a small area to build my coop and run. It will be long and narrow, but comfortable for 3-5 hens. I have drawn out this very rough design in a letter to my son who is in New York for 2 years serving a mission for our church, and he is a builder in the making. He won 2nd in the nation last year in the SKILS USA carpentry division. I wish he was here to build this, but he is doing better things so I simply have to write him and show him what I have in mind and ask for his opinion. Anyway, I thought of doing a simple barn style, about 8 ft long and 4 ft wide. It will have nest boxes on the one end and they will be accessible from the outside. Up in the small roof top I may have a couple nest boxes or possibly simply have a roost up there. There will be some screened windows up there for ventilation.
