Degus have a long gestation at 86-93 days and an average litter size is 6, although this can range from 2-12. Degu pups are born quite developed, with full fur and open eyes and so are able to explore within a few hours of birth. Male degu help raise the young, so can be left in with the female although it is recommended to remove him for the four days post birth to prevent him mating with the female straight away. Pups are weaned at 4-6 weeks which is when they need separating out since female degu can become sexually active as young as 7 weeks of age. Male degu become sexually mature at around 12 weeks.
