I have 2 Cayuga ducks that came from McMurray hatchery. At their one year molt they grew white feathers. Whats up with that ?? They were a beautiful emerald green/iridescent black prior to this molt. Here are photos. She gets Purina duck food. Sometimes Neutrena All Flock. She gets to go in a clean, non stagnant pond and out in out field when I can watch. None of my other ducks molted to non standard colors for their breed.

Wow! that's a pretty color
