How many joeys does a kangaroo usually have?

A kangaroo usually has only one joey at a time. Kangaroos are marsupials, and like other marsupials, they give birth to live young that are very underdeveloped. The joey is born after a very short gestation period, and it is then carried in the mother's pouch until it is fully developed. The joey will typically stay in the pouch for several months, and it will continue to nurse from its mother for up to a year.
