What is the name of person who invented chickens?

There is no single person who invented or created chickens. Chickens, like other species, have evolved naturally over millions of years through processes such as natural selection and speciation. Domestic chickens, commonly known as Gallus gallus domesticus, are believed to have descended from the red junglefowl (Gallus gallus) through a process of selective breeding and domestication that began thousands of years ago in Southeast Asia.
