I have a group of males and found out that 1 of my "boys" is in fact a girl. She is currently with her brothers who are about 3-4 weeks old. The breeder i got them from says he doesn't have anymore girls available right now but will in 2 weeks. He said she will be fine with the boys for two weeks but I'm a little worried. Will she be okay? Should i separate them now and find some girls from someone else?
