A Variety of mice have the same gestation period.(field, house, fancy, and meadow voles). Have a gestation period of 21 days. From Insemanation through incubation and birth is a total of 21 days. Normally a mouse will give birth from 6- 10 Pinkies(newborn Mice) however it is not unheard of to see upto 20 pinkies at birth. However when this happens likelyhood of a 100% survival rate is rare. Along with birth defects.(no eyes, mouth, ears, and or appendages).
