2 blue wyandotte eggs hatch, two totally different colors?

[happyhens44]

2 of my wyandottes hatched ones got a light gray head with a yellow body... and the others black with a tiny bit of white on the bottom?

Are they different colors because there different genders, if so whos the roo?

Nope, they're different because blue doesn't quite breed true. Your yellow one is actually a Splash Wyandotte.

You see, blue as a color is just one allele. Having both alleles of blue makes the splash coloration. Having none makes the black coloration. So, when breeding blue x blue and selling them as such, you actually get 50% chance of blue offspring, and 25% chance of splash or black.
