Muscovy male aggression

[Penpal]

I'm glad I looked at this thread again. We had both Muscovies and Khaki Campell, a mallard duck. They never mated with each other. Maybe because there were enough of both kind. Don't know, but when I got the Musovites that is what I read, that they don't cross.

My Muscovy drake has never mated with any of my Runners or Buffs.
