Chickens tend to be creatures of habit as much as the rest of us. Feed them in the coop as always, maybe scatter some scratch and such in their yard, provide additional clean water in areas you 'would like for them to hang out' (in addition to water in coop/yard ) Call them in at night before it gets to be roosting time , maybe 1/2 hr-hr before dust. Feed birds where they've always been fed, and they'll keep coming back. To eat, and to roost.
If your birds haven't been bothered by the owls or coyotes while penned, they really shouldn't be bothered by them if your coop door is shut. Free-ranged chikens need their home still.
It's a transition period for you as well as for the birds. You can't expect them to get their 'street smarts' as they walk out the door and into the world. You may make a few mistakes while you work things out, you may even suffer loses, but you most definitely will see some very happy hens.
