Okay, so they know the coop is home and they're free ranged before so they know how to get home. I still say you shouldn't loose hope till after dark. Especially if you haven't found any signs of struggle. I've lost four birds to attack and there was either an entire carcass left or at least quite a pile of feathers.
Once my flock was scared by a predator and the rooster took them off and hid them far away from their usual range. They wouldn't come out when my husband called but did come when I went and gave their "treat" call.
Walk around calling for them now...check in trees at dark...don't lose hope yet. Once I bought a new hen and she disappeared for over 2 weeks before suddenly returning!
