I just got my chickens today and yesterday we built an integrated coop and run. The coop is up off the ground over a bit of run, with a larger area next to the coop. Its like the playhouse coop, if you're familiar with that. Total about 4'x9'. I plan to let the chickens out in the morning when I leave for work (7am) and leave them out all day until it is dark (right now about 8pm). I have the food and water hanging below the coop right now. Do I need to provide them with additional food and water in their coop for nighttime?
