My Muscovies free range every day. They are let out at dawn and put themselves to bed around dusk/dark. They were originally locked up most of the time, just let out when I could watch them. Now I let them all out. All day every day. Mine are not wing clipped, and yes they fly, but they stay on their own turf. I swear they know where the property lines are! They go to the barn, all over the front yard, but they never leave the yard.
I just don't think yours recognize their home yet. Keep them locked up for a week, and they should be fine.
