If it is of good size, it's eyes are open, and if it has fur you probably should. But I just happened to find 2 baby mice a couple of weeks ago. They had fur, their eyes were open, but the were pretty small so I put them in a long aquarium with shavings, wood, seeds for my parrots and wild birds, and water, and they are doing just fine. I would take them in just in case. Although, once you take them in and raise them, you cannot put them back outside because they will not have any idea about how to find food and as a result they will die. If you take them in, be sure you can do a little care everyday and every week. Also make sure you have a lid for the house you put them in because mine have jumped out numerous times!! Mine are on the way of being hand tame and I intend to teach them numerous tricks, so it should be fun! Hope this helps...
You should be able to hold a feeder mice in approximately 1 or 2 weeks. It depends if the mouse is vicous or not. If the mouse is comfortable around you the third day. The mouse should be comfortable around you. Hope my imformation helped you.
Its usually 6 weeks sometimes 5 weeks. You should wait for at least 12 weeks before breeding the female.

The baby mouse can leave it's mother when it's about four weeks or older. At that time, the baby mouse is fully weaned of mother's milk. The baby mouse should also be eating solid foods as well.
