sexing muscovy duck
Muscovies can not be sexed by color to the best of my knowledge. Can you post a picture of your bird? Drakes generally mature at a third to 50% larger than hens.
Muscovy drakes do not get a tail curl. That is common only to mallards and mallard derived breeds.
Hey, it's all about learning. You did nothi8ng wrong, and learned something about ducks today.
nikki, looks like a hen to me.
