A really beautiful complex with the chickens worked into your landscape in a way few people accomplish.
Unfortunately, almost no information that would help people duplicate the actual coop -- which looks well-ventilated and thoughtfully laid out from what we can see of it.
You have quite the set up for your chickens. Funny, isn't it, how things grow from a simple start of "let's get some chickens"!
My only concern is that you used chicken wire all around the coop and run. Chicken wire is NOT predator proof. A more secure option would be to use hardware cloth.
I would have liked to see what the coop builder did with the coop. What does it look like inside? What are the dimensions, that sort of thing.
I do like how you used all of the old bricks to cover the bottom of the small run. Kind of looks like an old brick road! Is it easy to keep clean?
