Just a big of friendly advice. Consider how easy a coop is to clean. I personally would not build a coop I had to bend over to get into.
This "coop" I gave aways as new chicks needed to be trained togo in and not easy to crawl under. I did not like chcikens poop on my hands. and knees. They back however opened fully for ease of cleaning.
When I build the new one it will be raised with both sides able to open for easy cleaning I think. I will tweak it. I mostly wanted to see how they did in colder weather in it. Also hot weather. How predators dealt with it. Thinks like that. I know the perch is to close to the back wall, tail rub and look messed up.
