It might just be hormones but I wouldn't take any chances and keep them separte at all time. It only takes a few seconds for one to get hurt or your girl lose the litter.
I just gave my aunt one of my girls. I couldn't get passed the fighting and she offered her a great home with no other pets.
Sorry I don't have any advice on how to stop it.
