Good to know. Clean the sound and apply ointment as necessary. Keep her separated and she should heal just fine. :) Don't use hydrogen Peroxide. It can be very painful, and also kills the living tissue in large wounds.
I usually do about a tbsp per 8oz of water. I have never seen a real ratio...
What part of her body is injured? Can you post photos? You will first want to treat for shock. Offer her sugar water and electrolytes.
She may be mellow because of shock, did the hawk pick her up and drop her? If so, it could have hurt her legs in the fall. Keep her in a warm quiet place...
