Pregnant mice2007-11-24 22:14:39

How long does it take a mouse to have babies after she conceives?

Answers:

18-21 days. Keep in mind that females can become pregnant at only 9-10 weeks old, so unless you separate your babies after they are weaned (31/2 weeks) you're going to have another generation and will soon be knee-deep in mice!

Good Luck.

In a bout 3-5days.

12-18 days can keep having them. I used to breed them for feeders. Meaning she had them she will be prego again, and in a couple of weeks more babies.

mice can be a huge mess you should probably kill the pregnant mouse

I usually expected them at about 17 days.

about 10~15 days

I believe that the gestation period of a mouse is any where from 16 to 21 days.
