Baby goats are called kids. Female goats are referred to as "does" or "nannies;" intact males are called "bucks" or "billies;" and juveniles of both sexes are called "kids". Gestation length is approximately 150 days. Twins are the usual result, with single and triplet births also common.
Less frequent are litters of quadruplet, quintuplet, and even sextuplet kids. Birthing, known as kidding, generally occurs uneventfully. Just before kidding, the doe will have a sunken area around the tail and hip, as well as heavy breathing. She may have a worried look, become restless and display great affection for her keeper.
