How smart are chickens?
They may not figure this out without help. Be prepared to go out just after dusk and put them where they're supposed to be every night for at least a week. Slowly, more and more birds will figure it out and go to bed on their own, and then suddenly, one night, all of them will. And then they'll coop up by themselves and you wont' have to do the nightly chicken catching any more.
Don't think so. Mine always get their food and water outside of the coop. It depends on how early you plan to get up to let them out. If you're letting them out around the time they wake up--ie when it's light out--then they'll be fine. They don't need food in front of their faces 24/7, just when they are awake and active. Kind of like people.
They have a natural instinct to roost in a safe place at night, and once they've decided on that place, they always go there. You can train them to coop up where you want them by putting them where you want them every. single. night. until they "get it."
We're at this stage with our pullets right now, too. I've moved them from the brooder to the pullet house in the pasture, and while they know how to leave the coop, they're not very good at going home yet. So every night just after dark I have to go out with a flashlight and find the little beasties, and put them to bed. But I only have to do it for a week or so. Eventually, if the place you want them to sleep in is acceptable to them (high, dark, feels safe) they'll go there. Especially if it is the best option around.
