Thanks everyone. One day I will try my hand at building one myself. Its too hot right now and I'm too busy. The chickens seem to enjoy the new coop. They have a lot more headroom above the roost compared to the old coop. They were right up next to the roof in it. This one is so much nicer getting into. The old coop was about 4 1/2 foot tall inside and it was no fun getting into, especially with the roosts in the way. This coop stays much cooler inside and has a lot of good airflow. I may try to insulate the underside of the roof though at some point. Probably before winter. I just need to decide what to use and how to put it up.
I may also figure out a way to run the roosts front to back instead of side to side for more space on the top roost. Its a tight fit for all six of the chickens right now but one usually sleeps on the floor anyway because her wings were clipped way to short by the previous owner and she has trouble getting up on the roosts. Anyway, I'm very happy with it and it should do the job for quite a long time.
