Sorry about Miss Caroline.
Could you trim some of the feathers around the wound and post another picture?
After you trim the feathers and post a picture, I'd start by flushing the wound copiously with either saline (homemade if you'd like), chlorhexidine, or dilute betadine. The purpose of this, is to flush out any contaminants out of the wound. Once the wound has been flushed adequate, I would apply a coating of a antibacterial ointment like Neosporin to the wound. Preparation H is one of my favorites as it increases the respiratory comptent of the epithelium, thus encouraging fibroblast growth.
I do see you applied Blu-Kote, contrary to what some people will tell you, it's best not to use it with wounds, mainly because it contains alcohol, which can be quite damaging to the wound, and not only that, it stains the wound purple which makes it quite hard to observe the wounds real color.
Since this is a bite wound, there is likely an overgrowth of bacteria on the wound, and will eventually move to the the rest of her body. In a case like this I would start her on antibiotics. Do you have any on hand, if so what do you have,, and how many pills?
Keep her in a warm, stressful free area, that's away from flies, with feed/water provided.
itās a lot worse than pictured but I couldnāt get her to let me touch her much.
