Mine go in depending on the weather. If it's been a sunny hot day they'll wait until it's dark to all go in. If it's been cooler, overcast, and/or windy they start filing in as soon as the sun starts going down. Its always fun to be out when they put themselves to bed and within minutes they go from scratching around the run to filing into the coop one after the other. The first few nights I had to go put them in the coop and up on the roosts, then they did it themselves after a few days. They learn quick. When I go out to check and close things up I go say goodnight through their window (their roosts are right by the window and whoever is closest comes over to watch me) and close it and then go close the pop door. I like my nightly ritual of "putting the girls to bed" lol. Much easier than my kids!
