I'm sure the "original" duck owners would say that only the originals belonged to them. They would not claim the ones that are grown from the several generations that have come from just those few. You're right, if my birds got into their yard, I'd have a wing-cutting party. These ducks are so strong, I thought I was going to break my wrist when I grabbed hold of one while it was mating and it flipped around.
Yeah muscovies are strong i completely agree mine that i didnt hand raise (but still they let me pet them and stuff just no holding) when it comes to wing clipping just, its pretty stressful
With most of my muscovies i do this thing called arm training where i train them to sit on my arm from when they first get their flight feathers and its great when they need to be picked up, they dont struggle or try to get away just put them on my arm and boop they stay
