I would if possible, place her in a dog crate or cage inside the coop with others while she heals.
You have been getting great advice so far on handling this, but I just wanted to add a little history of my two polish hens who were a part of a large mixed multiage flock. The polish may be the lowest in pecking order--mine usually hung with the banties, rooster and hens. They had been feather picked on their heads as young pullets, one was blinded by a peck to the eye, and one was later scalped and left for dead by a young cockerel (she recovered.) Many people asked to buy them from me, but I felt I could give them the best care and protection. At 2 years old the smarter one was picked off by a predator during the daytime in my yard. At the age of 5, the half blind girl who always seemed slow mentally, was decapitated by 2 hawks who pulled her head off through my chainlink fence, and left her body undisturbed. I love the looks of the polish-type chickens, but I won't have any others because they tend to get picked on.
