So scientifically they’re classified as ducks? Interesting!Muscovy are genus cairina which is classification of duck (meat) where mallards are anas also known as dabbling ducks.
My Muscovies spend time in the water, but not near as much time as my mallard derived. I don't notice a difference between my mallard derived breeds as they tend to all stick together. 4 breeds 24 birds:No actual mallards.
