okay i'll give a small example of my coop, they usually sleep in a 2 X 2 dog crate that is elevated off of the ground by 4 pallets so about 2 feet off of the ground this crate also contains a nesting box, this is connected to an 8 x 8 chicken run that has a perch in it for them to roost on. it is at about the same height as my dog crate, however they do not sleep on the roost at night they go into the crate. should i make some small changes so they know that the nest box is for egg laying not sleeping?
