Domestic fowl refers to birds that have been domesticated for agricultural purposes, primarily for their eggs, meat, and feathers. Common examples include chickens, ducks, geese, and turkeys. These birds are raised in various environments, from small backyards to large commercial farms, and they play a significant role in food production worldwide. The domestication of fowl began thousands of years ago, with chickens being one of the earliest species to be raised by humans. Domestic fowl are typically bred for specific traits, such as egg-laying capacity or growth rate, making them essential to the agricultural industry and local economies.
