I misread what you said, my bad.
Polynesians may have ended up in the Americas, although the evidence is scant. Tlinglits had some fishhook designs, etc, that were similar, some decorative motifs as well, and maybe a few words, but not everyone is convinced that it's proof of interection or instead developed independantly with some common features coincidentally.
It's generally accepted that the Spanish introduced chickens to South America, but if so, they spread really fast all the way to the south, in under a century (something like that). Thing is those chickens tended to have dark bones, a distinctive trait of chickens Polynesians had, so they may have introduced them earler in visits.
There's some other clues, and ocean currents would have taken them here. Since they were the farthest rangng sea going people back in the day, extending all the way to New Zealand and up to Hawaii and Easter Island -the most distant spot from any other land on Earth - it would be most plausible that they did.
