I always see a lot of people asking which breeds of ducks can fly so i figued I would start a thread for all those people that need the info. This info that I'm listing is from my own duck experience with breeds that I have owned. Also info on clipping wings and other ways to prevent flying. Here's a few breeds I know of: Muscovy: Sometimes they males are too heavy, but they love to roost if they can. Call: Can Fly VERY well! Runner: Bad flyers Buff: Good flyers Khaki: Good flyers Swedish: Can sometimes be too heavy, but they do try! Mallard: Excellent flyers. Wood: Excellent flyers. Mandarin: Excellent flyers. Mixed Breeds: It depends on the mix, I have had some that can and some that can't fly. Everyone please feel free to add to the list Clipping Wings: (my method) I clip all my birds on the right side. This makes it MUCH easier to check and make sure everyone's been clipped.
