We saw both the rams and ewes were together during our trip down the Yakima River Valley. We thought we might see some contests for breeding rights between the rams, however there were none and honestly, we were more than happy to just see all the sheep. Bighorn Sheep facts: Both rams and ewes grow horns that are not shed but continue to grow throughout the animal's life. Ewes' horns are small and pointed; rams' horns are larger and curl. It may take a ram 7 to 8 years to develop a full curl. A dark band, called an annulus, forms each year on the horns during mating season. By counting these bands, it is possible to closely estimate the animal's age.
