The gestation or pregnancy period of the Red Kangaroo lasts between 6 and 7 weeks. They will most often give birth to one offspring, or joey. The baby Kangaroo is extremely small when it is born, being roughly the size of a bean. After the joey is born, it will crawl up the mother's fur to get inside of the pouch.
Duration [edit]. For most species, the amount a fetus grows before birth determines the length of the gestation period. Smaller species normally have a shorter gestation period than larger animals. For example, a cat's gestation normally takes 58â65 days while an elephant's takes nearly 2 years (21 months).However, growth does not necessarily determine the length of gestation for all species, especially for those with a breeding season.maller species normally have a shorter gestation period than larger animals.
