Originated in New York State, USA. Its conservation status world-wide was listed by the FAO in 2007 as "not at risk".
 
Cayuga Ducks may lay some 100–150 large eggs per year. At the beginning of the laying season the eggs are dark and may be almost black; they gradually lighten to the usual pale greenish blue or almost to white by the end of the season.  If they are to be hatched, the incubation time for the eggs is 28 days.
 
They are very good for free range duck farming system, and they enjoy eating snails, slugs and most other insects. The Cayuga is quite weather-hardy and happy to forage. If you have the space to allow your ducks to free-range and forage, they will be excellent at finding the bulk of their own food.
