I am building my coop this summer! I have the floor finished today. It is covered with vinyl, and on a sturdy frame. The coop is square, so of course 4 corners. I am wanting a coop that is easy to clean. I am willing to do extra work now, so I can save time every month when I clean the coop. Vinyl floor saves time, I learned that already. Large doors where you can just pull out the bedding. Hanging feeder and water (hanging water splashing too much?) Any other tips? I was wanting to make rounded corners so crud doesn't get stuck there, but I don't have resources for that. I was going to paint it inside too.
