My chicks will be in the coop (and out of the dining room!) for the second night tonight. Yippee! Since they're so young, should I leave food and water in the coop for them? In the house I would sometimes hear them wake up at night. When do I stop feeding them constantly? Also, I just built a roost in the coop, its about 2 feet off the ground. Will they need a ladder to get on it? Thank you!
