Both stitches and bandaging can seal bacteria in and set them up for infection. Most of the time it's best to leave them open. Once it's flushed out well, then apply a petroleum based ointment, a plain triple antibiotic ointment or neosporin that you can get in any first aid dept works well. Keep the wounds covered in that, reapply as needed to keep them covered in it. That will protect them and keep them moist, which will help healing. I would keep here where she can't be pecked at by other birds, they are attracted to red, and blood, and could make the wounds worse. A wire crate in the run with the others is usually least stressful and makes reintegration easier after. I would also use towels or puppy pads in the crate as long as the wounds are still open, to help keep them clean, loose bedding can get stuck in there, as well as dirt if she's roaming. Once they scab over, that's no longer a worry. As long as there is no infection, she should heal up well and be fine after, though it will take some time. Scabs may be very thick when they form, they will gradually come off on their own. Signs of infection would be a bad odor (you will know), redness or swelling more than the injuries would suggest, any pus or discharge from the wounds.
