Manx Rumpies

Bird

The Manx Rumpy, also called the Rumpless Game, is a breed of chicken which lacks a tail and rump. Unlike the Manx cat and tailless poultry that were common on the Isle of Man in 1871, the Manx Rumpy did not actually originate on the island, but was so named because of its resemblance to the Manx cat, which also lacks a tail. Manx Rumpies are a very old breed from the Persian Gulf – their first name in English was the Persian Rumpless – but they are rare in the West.
