It's very normal in white birds and she will turn back white again as her new feathers grow. Welcome!Hi everyone! My name is Denise and I am fairly new to easing ducks. My male and female Peking ducks were hatched in April. I have a question I hope someone can give me some clarification for. My female has recently moulted, but her feathers have now come back in pale yellow. Is that normal? At first, I thought she was dirty and needed her pool water changed. Now that she has fully changed over, I've noticed her whole body is this pale yellow color instead of pure white like my male. Has this happened to anyone else?
