Hello, I'm new to chickens and trying to learn as much as possible. Below is my coop/run I built. I live in the city and the only predators I would need to worry about are cats. Here in the SW we get about 3 inches of precipitation a year and maybe two or three nights in the winter below 30 degrees. Were the coop is placed the summer sun will only shine for part of the morning and then it will be shaded. The whole structure is about 10 feet long, 5 1/2 feet wide and about 4 feet tall. I'm only planning on about 3 hens. Will this coop/ run set up work or will they need more of an enclosed structure? I still have to add a roost. Thanks.
