The Icelanic sheep or Kind in Icelandic, is a breed of domestic sheep. The Icelandic breed is a North European short-tailed variety of sheep, which exhibits a fluke-shaped, naturally short tail. The Icelandic is a mid-sized breed, generally short legged and stocky, with face and legs free of wool. The fleece of the Icelandic sheep is dual-coated and comes in white as well as a variety of other colors, including a range of browns, grays, and blacks. They exist in both horned and polled strains. Generally left unshorn for the winter, the breed is very cold hardy. Twinning is very common in Icelandic ewes, with an average birth rate of 175% - 220%. A gene also exists in the breed called the Thoka gene. Ewes that carry the gene have been known to give birth to triplets, quadruplets, quintuplets, and even sextuplets on occasion.
