Hello, I recently rescued a young muscovy drake. I am very unfamiliar with muscovy ducks and have some questions. I have one Welsh Harlequin duck and one indian runner duck. How many ducks does a muscovy drake need? Will he over mate my ducks? If I get another muscovy female duck will it stop mating the others? He is a very friendly duck and belongs to my sister so selling him is the last option I want to take. Thanks for the help.
