My current alpha flock is 1 pair of African geese, 1 pair of Buff Ducks, 1 Pair of Khaki Campbells, 2 Rouen Males, 2 Pekin Females, and 1 Blue Runner female. I have 1 male and 3 females of Swedish/Rouen cross that are mostly integrated with them, but not completely yet. This spring I'm getting 14-15 more waterfowl. They were going to be this: 2 Pairs of Muscovies, 1 Black Swedish female, 2 Blue Swedish female, 1 Rouen female, 2 Welsh Harlequin female, 1 Fawn & White Runner female, and 1 Chocolate Runner female. As you can see, everything is female except for my Muscovies. I planned it that way, because I heard flock don't have too much problem taking in more females. And since I heard Muscovies don't have much desire to mate Mallard-descendant ducks, and vice versa, I figure it would make integrating a lot easier. There could be one problem. I was also going to get a pair of Buff Geese. I'm not sure if my 'nice' goosey would take another gander into his flock.
