Cayuga lay black eggs???

[RedFreckleFarmette]

I know this is an old thread...but I got a Cayuga baby duck and I was so excited anticipating these black or dark gray eggs...her very first egg was like a dusty white lol. And every one after that one has just been an off-white color. NEVER gotten gray or black I was bummed but shes so pretty. Solid black with a head that glistens emerald green in the sun.
