Duck Adoption?

[veronicasmom]

Just an fyi, that is not a great ratio of males to females. At the very least, each male will need two girls, three is better. It can work for a bit, but if the drake overbreeds the single female, or the two drakes just keep going after one of the females, they can cause injury or even death. If you are going to keep the pairs separate, maybe it might work, but you might want to give some serious thought to getting a better ratio. And I am sure your female runner and a female Muscovy will be fine, but just as Miss Lydia said, do the intro carefully. My muscovies can be bullies sometimes. But all in all, I have 4 of them in a mixed flock of ten ducks, one drake and 9 hens, and things generally go pretty well, with the occasional hiccup.
Good luck!!

I have experienced that a single muscovy among (domestic) mallards can be quite lonely because since they are different species, mallards and muscovies have different means of communication. A muscovy will greet another duck with head bobbing and tail wagging and become somewhat frustrated when it never gets an answer.
I have a mixed flock consisting of muscovies, runners, a pekin and a mulard and they get along just fine, sometimes the mallards ( with the mulard) and the muscovies will form seperate groups, sometimes they will all stick together. They recognize each other as flockmates and companions, but there is barely any interspecific communication.

I would at least acquire two muscovies or mallard derived domestics in their place.
