We have a Muscovy that my husband brought home from a sale about eight months ago. She was raised on a farm and she's very sweet. We also have six chickens. The duck thinks she is a chicken. She stays with the flock, goes to the coop with them, has only swam in our pond once. Never attempted to get into our pool. She laid eggs for about two months and then went broody and actually hatched one of our chicken eggs. She seems happy and is healthy so I guess it doesn't hurt anything. But sometimes I think about getting another duck or two to give her companions of her own species. *shrug* What are your opinions?
