• These birds lay eggs ranging from olive green to pure white, blue, and dark brown.

Class, Breed, and Variety of Chickens

Fertilized embryos develop quickly, and chicks hatch approximately 21 days later. There is some debate about what the chicken’s scientific name should be. Chickens have been featured in art in farmyard scenes such as Adriaen van Utrecht’s 1646 Turkeys and Chickens and Walter Osborne’s 1885 Feeding the Chickens. The pseudo-riddle “Why did the chicken cross the road?” dates to 1847, or earlier.

Chicken domestication likely occurred more than once in Southeast Asia and possibly India over the most recent 7,400 years, and the first domestications may have been for religious reasons or for the raising of fighting birds. Each flock of chickens develops a social hierarchy that determines access to food, nesting sites, mates, and other resources. Despite the chicken’s close relationship with the red jungle fowl, there is evidence that the gray jungle fowl (G. sonneratii) of southern India and other jungle fowl species, also members of Gallus, may have contributed to the bird’s ancestry. This stimulates the hen to lose her feathers but also re-invigorates egg-production.

Improved breeds can weigh up to 4kg when they are a couple of weeks old. These birds lay eggs ranging from olive green to pure white, blue, and dark brown. Fragrant chicken meatballs are served with a creamy coconut sauce spiked with sweet and spicy sriracha. At the end of the incubation period, which is an average of 21 days, the eggs (if fertilized) will hatch and the broody hen will take care of her young. Individual chickens in a flock will dominate others, establishing a ‘pecking order’, with dominant individuals having priority for access to food and nesting locations.

These domesticated chickens spread across Southeast and South Asia where they interbred with local wild species of junglefowl, forming genetically and geographically distinct groups. Domesticated chickens freely interbreed with populations of red junglefowl. The chicken (Gallus gallus domesticus) is a domesticated form of the red junglefowl (Gallus gallus), originally native to Southeast Asia. Furthermore, chickens suit different purposes, including meat production, egg production, and ornamental purposes. Like other birds, chickens come in various breeds and strains.

Chicken, (Gallus gallus), any of more than 60 breeds of medium-sized poultry that are primarily descended from the wild red jungle fowl (Gallus gallus, family Phasianidae, order Galliformes) of India. Hens of some breeds can produce over 300 eggs per year; the highest authenticated rate of egg-laying is 371 eggs in 364 days. In the United States alone, more than 8 billion chickens are slaughtered each year for meat, and more than 300 million chickens are reared for egg production. More than 50 billion chickens are reared annually as a source of meat and eggs.

Although chickens are flightless birds, they do have a tendency to attempt flight. Hens lay eggs that range in color from white to pale brown and other pale colors depending on the breed. There are over 150 different breeds of chicken that come in various colors, patterns and sizes. The market for chicken meat has grown dramatically since then, with worldwide exports reaching nearly 12.5 million metric tons (about 13.8 million tons) by the early 21st century. By the mid-20th century, however, meat production had outstripped egg production as a specialized industry. For most of that period, chickens were a common part of the livestock complement of farms and ranches throughout Eurasia and Africa.
