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.
