Answer
Hello Kim,

    It is really hard to tell if one might be pregnant.
Since the one will not eat, let anyone around it and they have been fighting, I feel that it would be best to separate them as soon as possible (putting the one that is eating in a different cage).
    Look over the one that is not eating to see if she has any wounds on her. If she does and there are signs of infection (redness, swelling and/or drainage), she should be seen by a vet. If there are no signs of infection, hopefully being separated from the other one, she will start eating again.
    If you have anymore questions, please write again.
