You might be able to 'herd' them back thru the little doors.......
........or start training with the 'rattling treat can' in their area before releasing into big coop.
You could also rig a temporary fence near the door in the big coop, so they can't go far during the first 'door training'.
Matter of fact...hmmm... rigging another barrier area would be a way to train to the doors without supervision.
I've found having a 25' roll of 1x2x48" welded wire fencing around to rig temp pens to be invaluable.
