Ok, so here is the issue. We are first time chicken owners and didn't exactly know what we were doing when we built my coop, so the nest boxes are higher than the roost bars, my hens and rooster sleep IN the nest boxes and so the hens won't lay in some of the boxes because of how dirty they get, is there some way I can keep them from sleeping in the nest boxes? a few of them lay their eggs before i get up, any ideas?
