Chick wound help

I attempted to integrate my chicks into my two chicken flock, one of my hens is extremely aggressive and she did this to one of them. They were only in the coop for 2 days and did this I assume last night because it was fine yesterday. I’ve since removed all chicks from the coop and brought them back into the brooder and separated this one. What can I do to clean this up or is it a lost cause? No judgement but I won’t be taking to the vet as this is a meat bird and it’s not worth spending hundreds to save it. It’s very alert and eating and drinking. I’m probably going to send the aggressive hen to crockpot jail as I can’t have aggressive chickens in my flock.
