The Boreray sheep are the rarest breed of sheep in Britain. The breed has only really been recognised since the 1970s when 6 animals were removed from the island of Boreray and all registered animals can be traced back to these 6 animals. They were the domestic sheep of the St Kildan islanders and were kept as a “reserve” flock on Boreray by the islanders in case a problem occurred on Hirta (the inhabited island of St Kilda).
These sheep are primitive horned short tailed sheep and generally are light coloured with tanned areas on the face and rump. Some dark animals occur and also animals with scurred and occasional polled horns.
