Hello, I would like to know how many times does a duck change colors???? I mean really. When I got mine they were about 2 days old and yellow. Later they turned to a white downy fuzz. Next they are a beautiful white and fawn color. Now my husband tells me that my indian runners are molting. At 8 weeks???? Does this mean they will change colors AGAIN???? I love the colors they are now. I noticed a couple of ducks are getting a dark spot on there forehead. One ducks bill seems to be changing color also, a greenish spotty look. I love the yellow beaks. Maybe they will be fawn colored. What can I expect next?????
