We studied survival and causes of mortality for hens. Primary causes of death were from bobcat, coyote, and great-horned owls. Seasonal survival varied from 94% in fall to 76% during spring. Annual survival was 55%, meaning just more than half of all hens survived a given year. Given the low survival of hens, our findings suggest that looking at relationships between hen survival and production is warranted, as production in this population may not be high enough to ensure sustainability.
