ok, I am by NO means a duck expert...however, in my own observation....females are a LOT noisier than males....muscovys are quiet, either sex...but LOVE to fly about. I live on 5 acres, and have a small pond, and about 1 1/2 acres of trees. They love to forage in the "woods" and usually fly away for about a day or so, then come home. Water water everywhere...and not a drop to drink...why?? DUCKS! They will muddy any water they can find. But, the plus side...they are so comical...and i just love my muscovy's. The way they wag thier tails...and the hissing noises they make...Elvis..my biggest male..tooo pretty. Good luck on whatever you decide.
