All I can offer is encouragement. I've had some pull through and surprise me, and others that I was sure would make it and didn't. You are doing the best you can for your girl!
A mink killed three of four hens in one of my coops. Like you, I interrupted before he could get the remaining hen. Although physically uninjured, my girl was seriously spooked for quite a while. I moved her into another coop, and eventually, she became her old self.
I am sorry for your losses...
