It baffles me why I a google search for this comes up with nothing. I've found my ducks to be incredibly smart...smarter than my lap dogs, even. So far I have a female pekin who knows how to 'beg' (I think that counts), several more pekins who hop up and down for a treat, and a little muscovy girl who'll fly up and perch on my arm to eat on command. Her wings are half clipped right now, but I hope to work with her this spring and teach a few falconry commands. (A tentative wish.) Anyone else have trained ducks?
