I breed my own gerbils for a picky mojave female. Things to keep in mind. The females will kill each other so what's worked best for me is keeping one female with one male. I then keep each litter together in a grow out tank. If the females grow up together they won't kill each other. I average litters of 5 or 6 so keep that in mind. Besides that, go for it. It is a pain to breed them so if there is anyway she will take rats again I would try. Good luck!
