These eggs come from my flock and are all fertilized and ready to hatch. I have hatched several clutches from this breeding pair with excellent results. Black Cayuga ducks are friendly with an even temperament and beautiful black and green plumage. They are also prolific layers with my girl laying one egg a day all season with the first eggs of the season being a striking black color! Add these ducks to your flock, or start your own, and you won't be disappointed.
