My girls have a coop and big ol run... coop is octagon, 3 panels solid, the rest mesh (with a palapa over the roof for decoration- looks like a tiki hut from the house!). They're sleeping on the ledge outside of their nest boxes at the moment but we're putting up a roost for them shortly. My dad (who designed the gorgeous bit of architecture that is the coop in the first place) has proposed pull-down canvas panels over the mesh. I'm not sure from which direction the wind blows. I was thinking something far less glamorous... like thick painters plastic stapled up with some room for ventilation at the top. Anyone have some suggestions?
