Usually if you put them both in a new pen, she will but not always. You will have to wait a little to see if there is fighting especially if the Male Is trying to be dominant. Now,I always suggest putting them in a new pen, this is so they are each in a unknown place and territory and dominance still have to be established between then, this will reduce the chances of fighting and in acceptance. If a new pen isn't available, I usually get them out of the pen and put them each in a seperate totally dark box, with air holes for about an hour or half an hour. Then I spray them lightly down with 50%vinegar and 50% water, very lightly just a rush, then I put them back in the pen, this works 99.9% of the time. If the female is really aggressive then put her alone because most probably its Gene's and you dont want to pass that down. Good luck
