We have low roosts in the brooder so they are not snuggling on the floor. But at about 8 weeks when we integrate them with the older flock, there are no lower roosts so they do huddle on the floor for a couple of nights. After that we put them on the roosts for two or three nights, and they are like, "Oh, THERE it is!" After that they find their spot and they're fine. The roosts are about three feet up and I think they just don't see them right away.
