I was after the same coop, and had my hubby draw me up some rough plans. I built this coop. Here is the link.
Awww!!! I love it. Im working on my own now with a few modifications. I painted mine red also, like a barn. It's coming along nicely. Ill have to post pics once I'm finished. How's the metal roof doing for ya in the summer? I opted to go with shingles. I live in Texas and was afraid the metal would heat up the house in the summer months too much.
