My chickens are 17 1/2 weeks and 14 1/2 weeks. I had covered up the next boxes about a month ago because they were sleeping in them. They have been sleeping on the roost for a couple weeks now, after having to put them up there every night for a few nights until they got the hang of it. I read that I should uncover the boxes soon as some are (hopefully!) getting close to laying, but I'm afraid they will start sleeping in them again. Would it hurt to wait a few more weeks? Would it be bad if I waited until they start laying? I don't want them to get into a habit of laying eggs on the floor either. My roost is higher than the boxes, but not much, maybe a foot or so. (bad coop design, mistake of a first time chicken keeper!!)
