how many babies in a chipmunk birth?
Chipmunks & Their Young A newborn chipmunk litter usually consists of two to five naked and blind baby chipmunks who weigh in at about 3 grams each. At about 10 days old they begin to get hair, and at about 28 days old their ears open up. Their eyes open when they're about a month old, and they start being weaned onto solid food.
