Leyden Glen Farm, located in the upper Pioneer Valley of Massachusetts, is a producer of grass-fed lamb. Nestled amongst the rolling hills, it is owned and operated by Mark Duprey, Kristin Nicholas, and their daughter Julia Nicholas Duprey. They have been raising sheep since 1980 when they purchased four Romney ewe lambs, which are the basis of their flock today. Over the years they have introduced different breeds of sheep to create their own unique flock which thrives on the soils and hills of Western Massachusetts. Leyden Glen Grass-Fed Lamb is healthy and real, as they do not use antibiotics or hormones in their feed.
