Gallus gallus domesticus

Gallus gallus domesticus refers to the domestic chicken, a bird bred by humans primarily for meat and eggs. It is a subspecies of the red junglefowl, originally native to Southeast Asia. Domestication has selectively bred chickens for traits like increased egg production, size, and docility. Today, they are one of the most widely kept livestock animals worldwide, vital for agriculture and food security. Chickens have a diverse range of breeds, but all share common features such as a comb on their head, wattles under their beak, and the ability to lay eggs almost daily.
