What age? If they came from the same flock they already know each other. They do need to get to know their new coop. Keeping them locked in the coop for a few days to a week will reset their idea of what is home.
beware of shutting them up in extreme heat. If the run is attached to the coop, so that is the only two places they can go, I would not shut them up during the day time, even if I did have to put them in the coop at night.
