Some background: we have a divided coop, with four chickens currently in the smaller side. We just put them out there about 2 weeks ago. Because we're dumb, we didn't lock them in the coop at first, just let them go out in the run as they pleased. They don't go into the coop/house on their own at night; they usually snuggle up in a pile in the outside corner of their pen. And boy, are they NOT happy when we put them in the house at night! They try to get back out and make very unhappy noises. The house is plenty large for them (they're still small and it comfortable fits six), it has roosts and a nesting box, and shavings on the bottom. What can we do to make them like their house again? Should we shut them in for a couple days? Add water and food? We have some more chicks (fourteen of them!) that we're going to be putting in the larger section of the coop/run in the next couple days, with a heat lamp. Thanks to the advice I've found on these forums, we're planning on shutting them in for the first couple days so they get used to the coop as "home." Is there anything else we should do to make sure that they're comfortable?
