Well I have frequently herded mine in. You need a long stick to extend your reach. Open the gate and put a small bit of scratch inside the run. Then take your stick and walk out around the farthest girl. This is a case where slow is faster, you don't want anything panicked or running. Once you get into position, you slowly walk forward until the chickens move away from you toward the coop. Then stop, when they return to pecking, again take a slow step forward until they move again. If one moves trying to get behind you, just reach out your stick and tap the ground in front of the bird, and they will turn and head back to the flock. Again, stop once they start to move, start slowly moving when they stop. Tapping the ground and calling "Hut, Hut" which I don't know if that part works or not, but I always do it.
In a few minutes, without the flock in a panic, they will reach the gate, see the scratch and be in. If you have one that escapes, ignore that one, once you have the majority in, walk further into the run and pour out more scratch, enough to keep them occupied for a few more minutes. There excitement will be heard by the escape, and that bird will come towards the run, just walk out, not attempting to chase this bird, but rather to get farther from the coop that the escape bird is, if you are far enough from the bird, the birds attention will turn from you and back to the excitement in the run, probably not moving, but looking or pecking. Then step forward, and that bird will move away from you, toward the coop a place of known safety, and some exciting thing to eat. Some birds are hesitant, but again, step forward slowly, extending your arm tapping the ground and calling, and mine will go in. I use a white sorting stick that you can get at the feed store, but any stick will work.
As to calming your birds down, move slow when in the coop/run, and spend time there NOT trying to pick them up. Just set a chair in there, sit down and watch them. The next day put a bit of feed on the ground a couple feet away from you, and again sit and watch, each day move the feed a bit closer to you, and soon moving slowly, reach out and touch them, if they move off, let them. Eventually they will calm down. Grabbing them will set this back. Patience and slow and quiet movements are the key.
