If you are holding her, give her a good facial massage while she is in your arms. Chickens love to have their comb and wattles, their jaw line, and around their ears massaged. Be sure to end these sessions quickly. Better to pick her up, give her a quick facial massage (if she relaxes into it, she will close her eyes and you will feel the tension leave her body) Again, put her down at that point, instead of prolonging the "captivity".
For a while, I would keep her in the run while the others are out. Give her some greens there. An other thing you might consider doing is making a vestibule for your run. This could be as simple as an extra gate so you can herd the compliant ones into the run, close one gate, leave the second gate open, and herd her into that area. This will allow you to herd her without all of the flock drama of trying to keep the others from escaping. You shouldn't have to chase her, especially if there is more than one person involved in rounding her up. Simply walk slowly behind her. with a stick in your hand, or even one in each hand. you tap the ground in a rhythmic fashion, and use the sticks to "herd her" in the direction you want her to go. If she gets skittish, back off. Never get close enough that she feels threatened. When I herd chickens, I walk along, tapping the ground, and in a calm voice, tell them "go to bed." I repeat until they have gone into coop or run.
