my daughters senior project for FFA was developing a small farm sheep flock. she Crossed her St. Croix with the schools black faced Dorper and that's what we have been raising for 3 years. the Dorper really bulked up the body yet mostly still resemble the St. Croix. they all still shed is the spring but tend to look matted and need help pulling matts. they rarely get diagnosed with internal parasites and are excellent browsers of unimproved pasture.
