You will be surprised the first time you let them out how timid they will be about going very far from their coop and run. Mine only started about 6 weeks ago and they still only go about 60 feet away. They will come back to the coop at dusk if they are used to sleeping in there, so I would suggest letting them out at sundown with maybe an hour before dark. Stay out with them, pull up a lawn chair, and just hang out. They will head back to the roosts when it starts getting dark. Ours won't even stay out for long during the day when it is hot. They like their fans in the coop.
