Did you buy them as feeders or pets? The one time i bought a couple feeder females from the petstore, I found they were first, filthy...which is bad for mice as they are naturally pretty clean. Two, highly stressed and unsocialized. Three, because of their bad conditions before I bought them, I determined they wouldn't make good breeders anyway and got rid of them.



I would recommend buying baby mice, about 5 or 6 weeks old instead. You will need a few weeks to a month to let them grow older before breeding (once they are 8 weeks would be fine to introduce the males). Get the males, or some of the females from another store, to hopefully get unrelated stock. Clean all the bins and introduce the new males to their harum at the same time you return the females back to the now clean cage. I find this is the best way to introduce new mice with others. The first few minutes they are re-exploring their environment, the male will mark his scent all over the place to make it feel like home and the females will by then be familier with his scent and hopefully, his introduction would be smooth. Of course, not long after he feels comfortable he will probably mate or try to mate with the females.
