i had the same issue happen when my male beat her up....best thing to do is make sure she is warm...like 80....then you need to make sure she is eating and drinking on her own...if not then you need to tube feed her until she can be able to eat/drink on her own...i would also spray the wound with vetericyn...if you have it....you can pm me if you need help tube feeding her....i would make sure you have the tubing materials that you would need in case of a sick bird...i had to make one for one of my chickens in the winter and tube feed....she responded quick....main thing is to be very observant on how she is doing...and then go from there...
