Last night, I was surprised to see that my 11-week-old pullets had gotten onto their roost -- I wasn't really expecting them to start roosting yet based on what others on BYC have said. I didn't see them get up there so am not sure exactly how they did it. But now they won't come down. How long should I leave them up there to figure it out? An hour? Longer? Or will time not help and should I just help them down now and figure that they won't be able to do this until they're a little older? Or -- could they just be chilly or sleepy and not ready to come down? The roost is only a couple of feet off the coop floor (the coop itself is raised). On another thread, someone mentioned leaving a hen up there until the afternoon, but I would worry about food and water access.
