I was reading through some of the posts and thought I'd post pics of last year's coop construction in case it gives anyone an idea or two for theirs. I looked at a LOT of coops (online) for a year prior to building mine and wanted to incorporate a lot of ideas I had seen. I wanted a steep roof for snow load, an interior I could hose out, outside egg collection and it had to be EASY to clean. I've replaced the shavings 2 or 3 times since moving my birds in early last summer and it's always been bone dry. As you can see, I have two small vents close to the floor diagonal from each other (one being in the droppings pit) and a vent at the peak that runs the length of the roof. that was easy enough to install, I just didn't run the plywood all the way up. I covered the opening with roofing fabric (nylon mesh) to keep bugs from using it as an open invitation. The inside is whitewash and the outside is white stain. I'll probably paint the trim and give it another coat this year. And the reason I built it........ Hope I didn't bore y'all.
