They show the obvious influence of Malay and other oriental blood. They were prized for their large proportion of white meat and its fine texture. The Cornish has a broad, well muscled body. Its legs are of large diameter and widely spaced. The deep set eyes, projecting brows and strong, slightly curved beak give the Cornish a rather cruel expression.
Cornish males are often pugnacious and the chicks tend to be more cannibalistic than some breeds.
Good Cornish are unique and impressive birds to view. The feathers are short and held closely to the body, and may show exposed areas of skin. Cornish need adequate protection during very cold weather as their feathers offer less insulation than can be found on most other chickens. Because of their short feathers and wide compact bodies, Cornish are deceptively heavy. Due to their shape, good Cornish often experience poor fertility and artificial mating is suggested.
