Ooh, that looks nice.
I had a couple of thoughts. I've read that fence staples can work their way out of wood over time (especially if a predator pushes on the wire from the outside), so that will be something to check periodically.
Have you considered stapling some inexpensive fiberglass screening in back of your hardware cloth on your windows and vents? I just did this in my new coop because I had some screening left over. It's great...it helps keep flies out of the coop, and in the summer the mosquitoes can't get to my chickens when they're roosting at night.
