Nice size for a backyard coop. You should draw up plans and post on the coop page. I also like the hardware cloth under the roof we did the same thing I feel very secure and lots of ventilation.
We live in the middle of the woods and so far no predators. We have a 24 in skirt around the perimeter also. Again nice job!
You said you did the hardware cloth roof too. Any worries of bats roosting up under the roofing panels between that and the hardware cloth?
