I have 4 chickens currently 17 weeks old. I only found out a couple of weeks ago that you are not supposed to allow the chickens in the nest boxes until they are ready to lay. Mine have been cuddling up together and sleeping in them. When I found out that's not a good thing, I blocked off the nest boxes to force them to sleep on the roosts, thinking that next month I would open them back up when they are of egg laying age. Well darn it all, but one of them laid an egg below the roosting area. Of course then I opened up the nest box and she lays in there now, but they are all still sleeping in there at night. Did I permanently screw this up or is there something I can do to fix it?
