o wow!!! I had a very similar problem with Sage and her ex lover Jade. I got Sage first and I thought she was male, the pet guy said she was. So I went to the local pet store later on and got another male to house with her. and they ended up having babies, 3 babies, 2 survived. I wish you luck with your lil ones. . Since you are a formal gerbil breeder then good luck with the lil ones.
