While the Mandans are perhaps the most northernmost tribe known to raise chickens, they were also raised by tribes in what is now Latin America.

Sorry, but I just can't find any mention of pre-colombian chickens in the Americas. Do you have any links or sources prior to 1700?

[Araucana] originated from Chile, Pockets of Araucana can
still be seen in the Amazon Basin and in isolated areas in the high fincas of the
Andes Range. The usual colours are Lavender, Blue, Black/Red, Silver Duckwing,
Golden Duckwing, Blue/Red, Pyle, Crele, Spangled, Cuckoo, Black and White. Also
some non-standard colours. It is a prolific layer of good-sized eggs and a very hardy
bird. When the Spaniards arrived in South America, bringing with them their poultry,
they found that the indigenous Indians had their own breeds which soon crossed
with the imported stock.
