i hatched some eggs form my trio of crested ducks. my drake is fawn and white and my hens are chocolate. the drakes parents were fawn and white as well but i dont know the hens parents colors as they came from a hatchery. the ducklings are BLUE! i dont know how that happened but it was quite a surprise to open the bator to blue babies. does anybody know how this could happen? does it have to do something with the chocolate gene?
