I'm building a little coop right now, and thought I'd ask for ideas for the roofing. It's about 4x8x6. We live in Yuma AZ, where it gets really hot and not very cold, so I made it open on three sides. It's just chicken wire, but our yard has tall brick walls on almost every side, and a chain link fence with dogs behind it on the last side. We've been using wood of poor quality, since it was free, but between that and my lack of experience I'm thinking the roof shouldn't be very heavy. Hubby has been helping the last couple days, but I made most of it myself. Not bad for a pregnant lady with no experience.
