My 6 week old chicks are living in their nesting boxes. They sleep in there and I think they stay in there all day bc the boxes are poop-FILLED, and there is no poop anywhere else in the coop or run! I have wood shavings in the coop, but nothing in the nesting boxes. I was just planning to leave them vacant since they won't be laying for a while. They have nice roosts, and plenty of room, for now anyway. So how do I keep them out of there? I don't want them to get into this habit bc then, where will they lay the eggs? Plus, my eggs will be gross! Thanks!
