K&N’s Safe and healthy chicken

Chickens have a communal approach to the incubation of eggs and raising of young. Chickens will sometimes attempt flight simply to explore their surroundings, however, they will especially fly in an attempt to flee when they perceive danger or pursued by a predator. The rooster is larger and more brightly colored than the hen, he also has a larger comb on top of his head. Roosters can usually be differentiated from hens by their striking plumage, marked by long flowing tails and bright pointed feathers on their necks. There are many different breeds that come in a variety of colors. With a population of more than 24 billion in 2003, there are more chickens in the world than any other bird.

Animal Names Glossary

Chickens are featured widely in folklore, religion, literature, and popular culture. The chicken was the first bird species to have its genome sequenced. For instance, many important discoveries in limb development have been made using chicken embryos, such as the discovery of the apical ectodermal ridge and the zone of polarizing activity. Equally important, embryologists can carry out experiments on such embryos, close the egg again and study the effects later in development. Chickens are social, inquisitive, intelligent birds, and many people find their behaviour entertaining.

Africa

The chicken is believed to have descended from the wild Indian and south-east Asian Red Junglefowl which is biologically classified as the same species. Chickens (Gallus domesticus) are domestic birds that cannot fly. Many immature males (cockerels) are castrated (usually chemically, with hormones that cause atrophying of the testicles) to become meat birds (capons). At about six months, males produce viable sperm, and females produce viable eggs. The time between ovulation and egg-laying is approximately 23–26 hours. Males (called cocks or roosters) and females (hens) are known for their fleshy combs, lobed wattles hanging below the bill, and high-arched tails.

Flightless Birds

Specialized breeds such as broilers and laying hens have been developed for meat and egg production, respectively. Females (mature hens and younger khelovip live chickens, called pullets) are raised for meat and for their edible eggs. The chicken is perhaps the most widely domesticated fowl, raised worldwide for its meat and eggs. 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.

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. Domesticated chickens freely interbreed with populations of red junglefowl. Furthermore, chickens suit different purposes, including meat production, egg production, and ornamental purposes.

• An early study proposed that a single domestication event of the red junglefowl in present-day Thailand gave rise to the modern chicken.
• Middle Eastern chicken remains go back to a little earlier than 2000 BC in Syria.
• The life span of a chicken varies between 5 – 7 years although there have been cases of chickens living 20 years or so.

Individual chickens in a flock will dominate others, establishing a ‘pecking order’, with dominant individuals having priority for access to food and nesting locations. 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.

Like other birds, chickens come in various breeds and strains. The breed affects all the physical attributes of a chicken, from size to egg production, meat production, and feather quality. Dual-purpose chickens are suitable for eggs and meat.
