It's been really cold here and due to light, I haven't had eggs in over a week. I've still been checking and a few days ago, I notices poop in the nesting boxed. they have always kept them quite clean so I thought it odd. I cleaned out the nesting boxes the other day, and they are loaded with poo again. Are they sleeping in there b/c of the cold? Will they use them as nesting boxes again once they start laying again? They are a bump out from the coop if that helps.
