??? The Mesoamericans domesticated turkeys, certainly. Googling "turkey domestication" suggests that the Pueblo dwellers of the US southwest independently domesticated turkeys. None of the articles I saw talked about woodlands Indians of the northeast doing so.Again... I don't have the reference, but OTL, I believe there were sources citing turkey pens & demi-domestication pre-columbian. I want to say Iroquois or Cherokee, but that's only because they are a part of a hobby... Maybe the Algonquins??
Of course, once you've got Norse that know about domestic geese (?and chickens?), you may well get northeastern turkeys domesticated.
1) they're poniesChangeable ITL, but in OTL, according the sagas, Leif didn't. Bjarni, who sighted land south of New Foundland first, *did* -- some 2500 colonists with full farming supplies (seeds) and livestock (horses included). They were blown offcourse and turned back to join Bjarni's father (Eirik the Red) in Greenland.
Now, don't ask me how they got HORSES on LONGBOATS!I think the sources might be... misinterpreted?
2) the HBC got stallions (as in modern riding horse uncut stallions) up to the Selkirk settlement in York boats which are a lot smaller than a longboat, let alone a knarr. http://www.archive.org/stream/selkirksettlemen00belluoft/selkirksettlemen00belluoft_djvu.txt
I distinctly remember one HBC factor getting a horse all the way to Cumberland House, but I can't document that ATM.
