You can bring her into the house for a couple days..........if your hen does not freak-out. Most will not, but I do have one hen that when she injured herself, she could not be kept from the other birds because she threw herself violently against the cage.
If you can, bring her into the house, or garage...........a place where she is warm without being hot, has plenty of water/food and no one to peck or pick at her and away from flies. I would not cover her wounds with anything other than the neo. that you have. Let the air help heal the wound.
Do you have a dog? We do not have raptor problems with our chickens, but do have raven problems. I have been working with our dogs to RUN toward the sound of the raven - to discourage the ravens from landing here on our place.
You migh also try fishing line strung along the top of your run - make it kind of like a spider web - this help to keep air assaults down (also cds that swing and move in the breeze).
