My coop and run are attached, I just left the door to the coop open and they went about thier business of going into the coop at night to roost, and playing in the run during the day. I've heard that if you put a flashlight inside the coop at dusk the girls will automatically return to the coop to roost. After a month of this I was able to free range them and they always return to the coop/run at dusk putting themselves to bed.
