Which is the chicken breed shown in the picture?

Cornish chickens are a large English breed with white, black or red feathers. They are a heritage breed, meaning they've been bred for many years in a particular location with traits conducive to thriving in that environment. They are now raised by backyard enthusiasts and small farms. Cornish chickens are poor egg-layers and are bred for meat. A Cornish hen is female and can be any size.

Previously, the Cornish was called the Indian Game Chicken, and some sources and breeders still refer to it. Even though it was referred to as an Indian Game Bird, it was not developed in India. Rather, it originated in England.

The Cornish chicken is a hefty bird with closely-knit feathers giving the chicken the appearance of a more slender fellow. Their feathers are a mishmash of colors that commonly include iridescent greens, brown, and blue; however, they can also come in white and buff.
