Muscovy are the only domestic ducks that are not derived from Mallard stock. Originating from the Caribbean, Africa and Honduras where the native culture values them for their meat, Muscovy aren't really ducks, but rather large perching waterfowl. They are very laid back and can be quite social with people. They can not quack but make a hissing sound while they wag their tails like dogs!
We have found our Muscovies to be great mothers and very good foragers. Typically laying around 180-200 Jumbo sized eggs per year. Males typically weigh 15+ lb while the hens are 5-8 lbs. Some people consider them ugly because of the large red warty caruncles above the beak and around the eyes. However, they are very personable and interesting birds, and quite intelligent. Trust me they'll grow on you.
We allow our hens to go broody and take care of their own young. The number of ducklings available can be unpredictable. We also can't tell sex until 8-10 weeks.
