Here is my urban coop. I built it with plenty of ventalation for the Arizona heat. There are two doors, one to get into the coop and one to get into the roost. The chickens seem to really like it. The nesting box was built on the roost door and opens up aswell. You can see that there is the PVC feeder and waterer with two nipples. The waterer holds three gallons. I also have a quart waterer hanging on the right side. We had a monsoon rain last week and the chickens did really well.
