I tend to let my chickens be, but Vetericyn and plain Triple Antibiotic Ointment, or at least the ointment once or twice a day would be what I would do. The skin is mostly removed including around the eye, so a great risk of infection is there. You can wait until dark, and with a flashlight or headlamp, apply the ointment. But I would keep her in a dog crate with food and water to keep her wounds from being pecked, leading to cannibalism. She still could see the other chickens and stay part of the flock. But watch out for flies. They can lay eggs and cause maggots to infect the wounds. The ointment may help to prevent that.
