Same chick type out of different color eggs.

[LDuck]

Hi, I have broody hens hatching eggs where there are different eggs laid by different hens. I have a single rooster (white silkie) fertilizing the eggs. I am seeing the same chick coloring (variances in leg, feathered legs and skin color). One came from a white egg and one from a brown egg. My brown egg layers I have are Cochin, Light Brahma, Silver Laced Wyandotte and Buff Orpington. My white egg layers are a White Japanese Bantam and a Buff and Self-Blue Polish frizzles.Both eggs were hatched under a hen that is Light Brahma over Japanese Bantam. Is there something I am not understanding in chicken genetics?

Probably, it is a very very complex subject.
