St. Croix hair sheep are the ultimate low input animal. You can put them in a field that would starve a cow and sheep find a way to thrive. The sheep do a great job controlling invasive species like Autumn Olive and Sericea Lespedeza. They also eat many of the forbs that cattle will not like golden rod, iron weed, multiflora rose, ragweed, Queen Anne’s lace, and the list goes on. They have been the perfect complimentary animal to our cattle.
