Thank you

Pls help! I posted this in the "emergency" section but idk if I did it right, I'm still trying to navigate through this site.
I recently got 6 red sex link hens (approx 18 wks old) Today my American bulldog pushed his way in the run as I tried to get in & attacked one of my hens

I got her out of his mouth but she has 2 small puncture wounds and 2 larger ones with blood. I applied pressure, washed them, put corn starch and then neosporin on them. She was already showing signs of a "cold" and rasping or rattling a bit, now after the attack she has clear drool coming from her mouth. Im so scared. I gave her fresh water, food and oatmeal. She put herself in a corner for a few hours and had her head down, tail down and her eyes were closing taking shallow breaths. She finally "woke up" a bit & had some oatmeal and a cpl sips of water. She still has drool coming from her mouth & wet nostrils. Is it from the attack or the cold? What should I do!? My heart is broken!!!
