Muscovy color question...

[mystry]

I have 3 muscovy's that are all white except for a "smudge" about the size of a dime or smaller on their head. I am wondering if they are considered white or not? If not, what color are they. I don't have enough posts to post pictures yet. One has markings that remind me of the spots around a swans eyes, another one has what looks like eyebrows. lol The last has just a smudge on top of her head about the size of a dime.
Thanks for your help/opinions.

Are these young ducks/drakes. If you didn't know already Muscovies have carbuncles that are red and surround the eye. I have seen white muscovies with black smudges on them it's perfectly normal and I'm sure it's just in the genetics line. White birds of any type seem to sometimes grow these black feathers on them. The only thing is that it's against standard rules to show a bird with black foreign feathers

You mean like a cap? My white drake has one, he is the white bird shown below he's a couple months a this years hatch.

Mine look like the white one in the pic, without as much black.

Yup, they are simply white capped muscovy. Can also be called french white. Caps can come in black or chocolate
