1. I have 2 mystery ducks which had white feathers at first but overtime, they have brown feathers on their breast and grey feathers on their wings, could this be because they hang out with the Indian Runners and Anconas too much? or is it something else? 2. My Anconas have white,black and green feathers, are they Tri-coloured? Extra quick question: Can Indian Runners lay Blue eggs?
My Runner lays eggs that are sometimes blue, so yes to that. I don't know about the feathers question, tho. I'm guessing that the change occurred after a molt? Feather color should be controlled by genetics, not environment or pen-mates.
