I'm building an open air shelter for my first chickens. The weather where I am, in sight of the ocean (Malibu, CA) almost never falls below 40 and rarely tops 85. We get no more than about 15" of rain per year, so that's not much to worry about either. My biggest concern is wind. When the Santa Anas gust at 60mph, and the weather stripping hums up at the house, I want to make sure the chickens are safe. I've come up with this little 3 sided shelter. I'm almost embarrassed by the simplicity, but I'm on my own with a jigsaw and a cordless drill. Dh doesn't build things. It will be inside a larger, fully secured run. I will add a secondary access door in the closed end. The opening will face south, away from where the wind blasts down the hillsides. What do you think? There's 32 sq ft inside since I'm making it out of 4x8 sheets of plywood (110 sq ft total in the run). I'm not sure yet where I'll put roosts and nesting boxes.
