An adult female turkey is called a hen, while a female under 1 year old is called a jenny. Male and female turkeys that are less than a few months old are called poults.
Adult male turkeys are called gobblers. An immature male turkey that is less than 1 year old is known as a jake.
Male turkeys are larger than their female counterparts, and they have beards of thick, coarse, hair-like feathers that grow down from the center of their chests and resemble a horse's tail. Males also have brightly colored heads in shades of blue, red and white, while females often have grey heads.
