Domestic chickens belong to the order Galliformes - ground-dwelling, heavy-bodied birds with strong legs and short, rounded wings. Dozens of wild species in this order look remarkably chicken-like. Here are 21 of the most common.

Grouse and Ptarmigan
Grouse are the wild chickens of northern forests and tundra. Ruffed Grouse in particular look and behave like wild chickens - they are round, ground-dwelling, and forage by scratching through leaf litter.
Rock Ptarmigan go a step further, turning completely white in winter for camouflage against snow. Their feathered feet act as snowshoes - an adaptation no chicken has.
Quail
Quail are essentially miniature chickens. They are the same basic shape - round body, short wings, strong legs - but scaled down to 20-30cm. Northern Bobwhites, Gambel’s Quail, and California Quail are the most common North American species, each found in different habitats.
The Wild Turkey is the ancestor of all domestic turkeys. Benjamin Franklin famously argued it should be the US national bird instead of the Bald Eagle, calling the eagle “a bird of bad moral character.”
Pheasants
Pheasants are the most visually spectacular chicken relatives. Males often have extraordinary plumage - iridescent greens, coppers, blues, and reds - while females are brown and camouflaged. The Ring-necked Pheasant, introduced from Asia, is now one of the most widely distributed game birds in the world.
Guinea Fowl
Helmeted Guinea Fowl look like chickens wearing polka-dot suits. Originally from Africa, they are now kept worldwide as pest control birds - they eat enormous quantities of ticks and insects. Their loud alarm calls also make them effective “watchdogs” on farms.
