Cayuga

Cayuga ducks, a hardy breed of domestic duck known for their iridescent black plumage.
They were developed in North America and are known for their quiet, docile temperament.
Cayugas are considered good foragers and can be excellent layers, producing between 50-150 eggs per year.
When they first begin to lay, their eggs can be completely black, a unique characteristic that fades to white as the laying season progresses.
As the ducks age, they often begin to produce white feathers, which become more prominent after each molt.
