The Noon Family Sheep Farm is a MOFGA-certified, organic sheep farm. We have been raising sheep since 1970 and winter 50 to 60 ewes. Our original Columbias were purchased indirectly from the UVM flock dispersal. Since then the flock has evolved into a mix of Columbia-Rambouillet-Leicester-Suffolk-etc. bloodlines, including colored and white wooled brood ewes. We market value-added lamb directly at fairs and festivals through our lamb barbecue food booth. We also sell hay, wool, yarn, sheepskins and lamb at the farm, a part-time operation except during fairs and during lambing and haying seasons.
