The Cochin or Cochin China, is a breed of chicken.
The name Cochin came from the original Chinese name 九斤黄(in pinyin: jiujin huang), meaning nine-catty yellow, erroneously conflated with the then-current names for what are now parts of southern India and Vietnam, where jin is a traditional Chinese measurement of weight. In China itself, the name 九斤黄 is actually used for any large chicken or even a dish made from one.
This chicken was originally bred in China and later exported to Britain and America in the mid 19th century.
As a very distinctive breed of chicken, it apparently created a bit of a craze among poultry lovers in the English-speaking world, effectively launching poultry fancy as we know it today.
Not only was this breed one of the largest seen, with cocks weighing up to 5 kg (11 lb), but also its soft and very plentiful plumage, similar to the Japanese Silkie, makes the bird conspicuous by exaggerating its already large size. It was successfully bred into other birds.
