Duck eggs are generally white, but some breeds lay pale green/blue eggs. Some ducks, especially Runners, Mallards, Magpies and Anconas often lay pale green eggs, while others of the same breed lay white eggs, even if they both hatched from a green egg. The Cayuga duck breed lays a charcoal gray egg. But now, unlike chickens, where Marans lay chocolate eggs, and leghorns lay white eggs and Americanas lay blue eggs, the duck egg follows its own set of rules when it comes to its egg color. Leghorns lay white eggs and Marans lay dark brown eggs. But duck egg color doesn't follow these specific rules. It has to do with genetics and how long the breed has been standardized.

Eggs are initially black in color, but as the season progresses egg color lightens to white by the end of the season. The plumage of the Cayuga is uniformly greenish black and may become mottled with white as they age.
Keeping Ducks with Chickens Ducks and chickens can coexist fine usually. The only risk to raising the two together is that a rooster will try to mate a duck hen, and a drake will also try to mate a chicken hen. This is not a problem as far as a rooster mating a duck hen.
In order to produce clean eggs, nest boxes should be provided. Washing of duck eggs is not recommended. Washing eggs can damage the invisible natural antibacterial coating on the egg shell which may in-turn increase the risk of penetration of the egg by salmonella bacteria.
And while duck eggs are a natural, nutritious food, they do need to be handled and cooked with greater care than quality assured hens' eggs. Salmonella causes food poisoning with diarrhoea and vomiting. However, more severe cases can go on to develop blood poisoning or meningitis.
