Their life centers year-round on the needs of their flocks; men and boys are usually responsible for the protection and general care of the flocks, like shearing and milking, while women are occupied with the building of the dwellings, sheepfolds and goat pens; child care, and other domestic tasks, including preparing, spinning and dying the shorn wool; and tending chickens, the eggs of which are their only source of personal income. Women also keep household vegetable gardens, with some wild herbs used to supplement the family diet. When boys are old enough to help with the flocks, they accompany their fathers and are taught the skills they will someday need. Similarly, girls learn through observing and assisting their mothers.
