Tracking feather color changes. Vitiligo?

[Sheepheart]

Two weeks ago or so I noticed my black crested duck had a white feather in her floof and a black feather with white edges at the base of her neck on her back.
last week I thought I saw another white edged feather on the side/bottom of her rump but it must have been groomed out. I thought I had pictures but I must have deleted them? So I’m going to be taking pictures when I notice changes and posting them on this thread.

this duck is one and half almost two years old, and has t had any Heath issues since I’ve had her, and no behavior changes.

All ducks are prone to white feathers with age it’s just easier to notice in darker breeds, but she isn’t that old. I figured the one in her floof is from mating.

My cayuga started getting white feathers around that age, too - maybe even younger. It varies by duck.
