What Is the Difference Between Male and Female Ginny Birds?

The easiest way to tell a female, or hen, from a male, or cock, is when they are adults. When a hen lays her eggs, she prefers to roost in a tree or a field, where she lays up to 30 eggs, or one egg per day. She may lay her eggs from the end of March through mid-May. These eggs are about two-thirds the size of a regular chicken egg.

Both male and female Guinea fowl have a wattle. The wattle is a fleshy growth on the bird's neck under the beak. When Guinea fowl are young, between 12 to 15 weeks of age, the male's wattle is more prominent than the female's. The male's wattle has thicker edges and curves out more from the neck than the female's. Between 15 and 16 weeks of age, the female's wattle also begins to thicken, though the male's remains larger into adulthood.

The size of the helmet, a backward-curving bony growth, on the Guinea fowl's head is larger on a cock than on a hen. The cock also has a head that looks coarse and not as smooth as a hen's head. In addition, the cock is larger than the hen. Many times, these differences are so slight as to appear non-existent. It takes a trained eye and experience to distinguish a Guinea cock from a Guinea hen by physical appearance.

Both hens and cocks have an unusual cry, but most often this cry is the best way to tell the difference between sexes. The cock's cry is a single syllable note, or more of a shriek, whereas the hen's cry is two syllables. The cock never makes the two-syllable cry. Many say the male's call sounds as if he is saying "wheat," and the female's call sounds as if she is saying "buck wheat" or "qua-track qua-track." Young cocks start making their cries as early as six to eight weeks. Hens generally do not start until much later.
