I got my call ducks at the beginning of June. I have two drakes (a black bibbed and a blue bibbed) and two hens (a white and a snowy). When will they lay eggs? How often do they lay an egg? When will they be fertile? If I hatched my owned ducklings would I get any other colors than the four colors I have? (I'm thinking, like, cats- if the parents are both tabbies, you can still get kittens that are black, gold, calico, etc....) Or do I need two parent ducks of the same color to make properly colored babies?
