Chickens descend from jungle fowl, which were carried out into the Pacific from SE Asia.

Yes exactly. We have chicken remains in Chile that are dated between 1304 and 1424. And we even have DNA confirmation from those bones that link them to modern Polynesian chicken populations. The tailless, blue-egged Araucana breed is still around today and is thought to predate Columbus

Ask a 5yr old. They've watched Moana a dozen times and can name a chicken character.
