No dear. I think it started on farms in third world countries where people handle chickens and ducks. I truthfully hadn't thought about migratory ducks. I've already been corrected in that area, thank you.
You also apparently didn't think about swans, gulls, sandpipers, herons, pigeons, doves, falcons, eagles, crows, tree-sparrows, magpies, etc. either.

What exactly were you thinking when you made those earlier claims?
