Thanks! I'm thinking of building the WCC as well. I live in Az and shade is a huge concern. With the layout of my yard, the only place that makes since, the normal design would not provide the shade that I'm wanting. So like you I thought about mirroring the coop, to enhance the roofs shade production. Thanks for the help! I'll be following and asking questions as you go along! Good luck
WCC build going on for me too right now - not as far along as Undrcvrpullets , but if you're interested , come over and take a look.
