Cochins were never a commercial success, but because of their large size, they were historically raised as meat birds.
Cochins originated in China, and for a short time were sometimes called Shanghai Fowl. They are super fluffy, with lots of feathers, which exaggerates their already large size. When they were first imported to the US in the 1840s, they caused an immediate sensation.
Blue Cochins were not among the first Cochins to be included in the American Poultry Association's Standard of Perfection in 1874. It took a bit longer for breeders to perfect the variety and they were accepted by the APA in 1965.
Blue Cochins are grayish-blue. As with all blue poultry, they do not breed true. When you breed a blue hen with a blue rooster, 50% of the chicks will be blue, 25% will be black, and the remaining 25% will be splash - a light color with splashes of blue and/or black over the body. Cochins are frequently described as "fluff balls." They are large chickens, with rounded bodies that are covered by an abundance of fluffy feathers. Their legs and feet are fully feathered
