Chickens are domesticated birds that are a subspecies of the red junglefowl. Hens, or female chickens, are typically raised for egg production and meat. Brown chickens, like other chickens, have a highly social structure and communicate through a variety of vocalizations, clucks, and calls. They are omnivorous, feeding on grains, seeds, insects, and even small animals when foraging. Known for their egg-laying capabilities, many breeds of brown chickens can produce hundreds of eggs per year. They play an essential role in sustainable farming, helping control pests and fertilizing the soil through their natural behaviors. Chickens also exhibit complex social dynamics, establishing a hierarchy known as the "pecking order."
