I believe this is a Norfolk Horn sheep, one of the British black face breeds. It survives on poor forage, cool but dry climates. Both sexes of the Norfolk Horn sheep have horns, but they are larger with males. It has a light build and is a very hardy animal. It is raised primarily for its meat. In the early 1900’s their numbers dwindled to one herd. Revival efforts began and by the 1950’s there were more unregistered stock. There were however, very few pure bred rams and in 1973, the last pure bred Norfolk ram died. Related breed, the Suffolk, and unrelated breeds such as the Wiltshire Horn and the Swaledale were used to produce animals that were 90% Norfolk Horn. In 1986, the Rare Breeds Survival Trust recognized the breed as Category 1: Critical. Their numbers have increased and in 2007, they were reclassified as Category 4: At Risk.
