We enjoy our Katahdin sheep. Our sheep are disease tested, very parasite resistant, and Codon 171 tested.  We have never had to de-worm our ewes or ram.  Our outstanding genetics produce hardy sheep that do excellent on pasture and produce healthy lambs. They have clean water, a variety of high-quality free choice minerals, and plenty of pasture to graze. They are given good quality hay when needed but not fed grain. Our ewes lamb on pasture and have great mothering instincts.
