Clun Forest Sheep

Clun Lambs Grazing

The McClain Clun Forest Flock was started with a diverse and excellent genetic base.  In addition to the original importation genetics common to all Clun Forest Sheep in the United States, the flock is improved and diversified with genetics from all four imported Dutch lines (FAF 025, OWE 227, TBV 071, and SAN 125).  With 30 ewes, the flock is one of the largest, if not the largest, registered Clun Forest Flock west of the Rocky Mountains.

Clun Ewes During Breeding Season

Over the years, we have tried many breeds of sheep including Suffolks, Hampshires, Oxfords, Dorsets, Border Leicesters, Cotswolds, and various crosses. The Clun has outperformed all of other breeds.  

The flock lives year round on pasture.  Our present pasture is predominately a very poor quality class 4 clay soil.  In the winter it floods heavily and is waterlogged, while in the summer it dries up like a brick. Despite severe drought for the last two summers, our mature ewe lambing rate was 185% in 2014.  In the winter, despite the waterlogged soil and flooding, the flock has never exhibited hoof problems.  On decent pasture, ewe lambs have a high rate of being bred to lamb as yearlings.  We rarely expose ewe lambs to a ram on the present farm due to the poor pasture.  As a thrifty breed, the Clun is able to thrive in any type of environment and produce accordingly.   On quality pastures, lambing rates of around 200% can be expected.   On lower quality pastures, the Clun will out-produce just about any breed as well.

The Clun is a very milky, maternal breed with the highest butterfat ratio.  This translates to high weaning weights.

Though the Clun is known as a top producer of prime British lamb, the breed’s most utilized niche is its use in the British Three-Tier Breeding Strategy.  For more information, visit:

High levels of worm resistance, and hooves that rarely need trimming, make them easy to manage sheep.

Put simply, the Clun Forest is the breed that combines top maternal qualities, prime meat, and high levels of hardiness.
