It is very hard to keep baby mice from dieing when the mother is not there. You need to feed them a substitute milk every 2 hours with an eyedropper. You need to keep them warm too. GOOD LUCK.
The best advice in caring for baby mice is to keep them warm, provide a safe and clean environment, and feed them a specialized formula for orphaned rodents. Make sure to handle them gently and avoid stressing them out. It's also important to seek advice from a veterinarian or wildlife rehabilitator for proper care and guidance.
After about two to three days you should pick the mice up but make sure the mother and father are not there. After about 2 weeks the mice will open There eyes and start to walk around a little. * mice will be very jumpy and should be separated so they do not breed.

At three weeks the baby mice are not fully weaned from their mother. You should keep the baby mice with their mother until four weeks. Then separate the boys and girls. The girls may be housed with their mom.
Get a female mouse and male mouse, keep them in the same cage, they are likely to mate or breed if they're alone together.
That depends somewhat on your attitude towards baby mice.
