My five-week-old babies went into their new outdoor coop today. It's a raised coop with a ramp and a door. So far, they've been hanging out under and around the coop, loving the straw bedding and the bugs. I'm concerned they'll never make their way up into the coop. We've been putting food on the ramp to entice them up and so far, two out of five have spent a little time in the coop and then come right back down. Should I physically put them all up in the coop before nightfall? I'm concerned they won't have enough food and water if we don't.
