Chicken General Characteristics & Facts
Species
Chickens belong to the species Gallus gallus domesticus, a subspecies of the Red Junglefowl.
Domestication
Chickens were domesticated from wild junglefowl in Southeast Asia around 5,000 years ago. They are one of the most widely domesticated animals in the world.
Size and Weight
Chickens vary in size depending on the breed. On average, they stand about 14 to 18 inches (35 to 45 centimeters) tall and weigh between 4 to 8 pounds (1.8 to 3.6 kilograms).
Feathers
Chickens have feathers that come in a wide variety of colors and patterns. Their feathers provide insulation, protect them from the elements, and aid in flight for some breeds.
Beak and Comb
Chickens have a pointed beak used for pecking, eating, and exploring. They also have a fleshy comb on top of their head, which can vary in shape, size, and color depending on the breed.
Lifespan
With proper care, chickens can live anywhere from 5 to 10 years or longer. However, their lifespan may be shorter if raised for meat production.
Social Behavior
Chickens are social animals that live in flocks. They establish a hierarchy within the group and have a complex communication system using vocalizations, body language, and displays.
Reproduction
Chickens are oviparous, meaning they lay eggs. Hens typically lay eggs every 24 to 26 hours, and if fertilized by a rooster, the eggs can develop into chicks.
Diet
Chickens are omnivores and consume a varied diet. They primarily eat grains, seeds, insects, worms, and vegetation. Commercially raised chickens are often fed a formulated diet.
Egg Production
Egg-laying breeds of chickens are prolific egg producers.
