I'm getting ducks for the first time this year, and, being in Poultry Bowl, I already have done quite a bit of research on them. I'm hoping to get either Khaki Campbell or Cayuga breed. According to my Avian Bowl Manual, only bantam ducks (Mallard, East Indie, and Call) and Muscovy can fly. A few can "maybe" fly. The manual lists both Khakis and Cayugas as non-flying breeds, but when I spoke to place I'm going to get them from, they said that Khakis can fly (I didn't ask about Cayugas, though I assume they are too heavy). I even found a video of the Khaki Campbells flying. My book is possibly outdated. Can someone give me the lowdown on the subject?
