My uncle had some for the longest time, he'd bought some for his pond and probably had them for close to 15-18 years, long as I can remember. His were never super skittish but I don't remember them being as friendly as mine, I do think mine were hand raised but I'm so use to hand raising ducks and having them revert back to being skittish when they grow upWe greatly enjoyed our muscovy.
We still miss them (dog attacks, followed by eagles...lost them all)
Very smart... you can train them easily, and they love so many food items, definitely not picky eaters!
