They should always be approached gently and cautiously. Give new arrivals and young chipmunks time to get used to your voice and presence, and let them get used to your hand in the cage before trying to pick them up. Hold them in cupped hands, and keep your actions smooth and your voice gentle. Breeding The best help you can give a chipmunk family is to leave it well alone. There is no need to remove the male, and the female will become very stressed if you take too much interest in her babies.
Gestation lasts around a month, and the babies are blind and hairless at birth.
They leave the nest when they are a little over a month old.
