I had read that if you put nest boxes in the coop too early the chickens could get in the habit of sleeping in them and that could cause problems later on when they start laying. So I have not put nest boxes in my coop since my chickens are still young (7/18/11 birthdate). My question is, when should I put the nest boxes in? Do I wait until they start laying? Or do I put them in just before they get old enough to lay so they have a chance to get used to them? Also, my chickens don't seem to like their roost. They prefer to sleep on the floor. I know at least one of them investigated the roosts because I've found a couple of droppings up there but I'm pretty sure it was Gabby who is my smallest and most curious bird. I have heavy breeds (Buff Orpington, Wyandotte & Australorp) so should I add a ramp up to the roost so they don't have to fly up or just let them sleep on the floor and take the roost out of the coop?
