EWES Female sheep are referred to as ewes. A ewe that has reached full growth and development weighs approximately 100-105 pounds. Ewes, like rams have horns that grow throughout their lives. Ewes horns are smaller in diameter and shorter. Her horns may reach 10-12 inches long.
Ewes live together in groups throughout the year.
Groups sizes average five to seven, but groups as large as twenty or more have been observed. Groups consist of ewes, lambs, yearlings, and young rams less than three years. Researchers have determined that desert bighorn ewes have home ranges of approximately 15 square miles. There is some evidence that when lambing season approaches, ewes return to the same area each time they have a lamb. Usually a mature ewe dominates the group.
