At dusk I go out to lock down the coop. Our sussex has been sitting a top the coop, I thought it was just being curious but now my orpington is doing it too. They end up getting down and going into the coop. Just wonder why they are doing this? Trying to get a high roost point? They are about 14 weeks and molting their flight feathers that were cut, so have to wait a bit to cut them again.
