Hi, I have 4 ducks: 2 female Muscovies, one male Muscovy, and one male mallard. My male mallard has been picking on the other male as well as one of the females. I'm thinking of purchasing two more females Muscovies to calm the tension. I can only find adult Muscovy hens right now. Since I raised my ducks as babies I am very close with them and they are my pets. My question is, if I buy two adult Muscovies can I tame them to be my pets too or will they stay somewhat timid or aggressive to me? Or should I wait until I can find ducklings. But even then I'd be worried that they would end up being males.
