Mystic Onyx Chick Weirdly Colored?

[Ahygre21]

I just hatched purebred mystic onyx chicks, or Atleast I thought I did. I separated my purebred mystic onyx hens and mystic onyx rooster and collected their eggs. 2 of the eggs just hatched, and one of the chick has white on it. Is this common? Or somehow did I mix up the eggs? The other tan colored laying hens I have are Rhode Island Red and ISA brown.

Do you have another roo? You say you separated them.
How long did you wait before collecting eggs?

I only have one rooster, which is a mystic onyx.

M.Os are mixed breeds, with silkie in them. It's very possible that some of them have recessive white just lurking around
