Chickens are omnivores.In the wild, they often scratch at the soil to search for seeds, insects and even larger animals such as lizards or young mice.
Chickens in nature may live for five to eleven years depending on the breed.In commercial intensive farming, a meat Chicken generally lives only six weeks before slaughter.A free range or organic meat chicken will usually be slaughtered at about 14 weeks. Hens of special laying breeds may produce as many as 300 eggs a year. After 12 months, the hen’s egg-laying ability starts to decline, and commercial laying hens are then slaughtered and used in baby foods, pet foods, pies and other processed foods.The world’s oldest chicken, according to the Guinness Book of World Records, died of heart failure when she was 16 years old.
The male can be differentiated from the female by its comb
Roosters can usually be differentiated from hens by their striking plumage, marked by long flowing tails and shiny, pointed feathers on their necks and backs (the hackles and saddle)—these are often colored differently from the hackles and saddles of females.
