You can do it if you have a long stick, and one or two others to help, but not necessary. This is a case where slow is fast. Open the yard you want them in. Put a small pile of treats just beyond the door, and a larger one further in.
Go out around the flock, so that they are between you and the opening you want them to enter. They should naturally, calmly move away from you. Stand there without moving until they stop. Using the stick to tap the ground, call Hut, hut, and take a step toward them slowly, if they don't move, take a second step and third until they move away from you towards the hut, when they move you stop, stand there, until they stop, then repeat.
If one thinks of heading the wrong way, just tap the ground in front of it, and she should return to the flock. If she gets by you, let her go, and work on the others. Eventually, most will get close enough and discover the feed, don't race, just keep slowly apply pressure until they move in to find the second treat pile.
That should keep them occupied, while you make another round encouraging the ones that got away. If you stay calm, they only be a bit nervous, and will be strongly attracted to the flock to move away from you and to see what treat they are getting.
If all else fails, I have used a fish net on a 5 foot handle.
