Fancy mice

Question
I have a mouse named Jackson and a fancy mouse named daisy i put them in a cage together for 3 months , now  later i have twelve baby mouse/fancy mouse baby's and i know that the they are daisy and Jacksons because daisy was not pregnant when i got her what do i do .

Answer
I'm not exactly sure of what the question may be. Are you asking how to care for the mother and babies, or asking what to do with the mom and dad? I would separate them right away, as mice can and will get pregnant after having a litter, sometimes even before the babies are weaned. They are very efficient breeders, and you can wind up with tons of babies in a matter of months. You will need to learn how to sex the babies as well when they are older so that you can separate the male babies from the mother and their female siblings. Make sure the mom has plenty of food and fresh water available, and make sure you keep her cage clean. You do not need to move her nest, and doing so may stress her out, but at least clean up around the rest of her cage and provide plenty of nesting material.

If you can let me know what exactly your question was I can better assist you.
