It is considered a primitive breed, hailing in origin from an island chain off the coast of Scotland. The Soay sheep project has been running in its current form since 1985 and is studying population dynamics, evolution and genetics, ageing and parasite infection in a natural setting. The Soay Sheep Project has been running in its current form since 1985, with continuous collection of information about individuals including genetic parentage, morphological data and life-histories. All of this attention means we catch and treat any problems early and then are able to send robust young Soay sheep off to their new homes. 81 Soay sheep living within the Village Bay area on the island of Hirta, St Kilda, Scotland 82 (57 49‘N, 8 34‘W) have been individually studied since 1985 (Clutton-Brock et al., 2004).
