Mystery yellow chick

[schambo]

Can anyone explain how this yellow baby came from a Lavender Orpington roo? Hen is an Easter Egger that appears wheaten coloured. My understanding is that lavender should act as black, and that would be dominant in this pairing. Slight chance that dad is a black silkie or a blue copper marans, but not super likely, and neither of those pairs would lead me to expect a yellow chick either!

Supposedly these two are full siblings! They definitely share a mother at least. I’m guessing the yellow one’s father must be the marans with some sneaky wheaten genes.

Pictures of possible parents are helpful?

This is mom (for sure, she’s currently my only one who lays green eggs). Easter Eggers mix of unknown parentage.

Possible father #1 (blue copper marans, rehomed about a month ago)

Possible father #2
Lavender Orpington. Apparently I don’t actually have a recent photo of him - this is him as a pubescent cockerel.

Yeah, must be the marans hiding a wheaten gene. Now 3/4 chicks hatched from that hen’s eggs are yellow, the other is grey.

The hen is Blue Buff(Columbian)in color, most likely Wheaten based. Both are Dominant.
Lavender would act as black, that's correct if he were the father, so the mother would make either leaky black, or blue Incomplete Columbian chicks.

That hen, & Blue Copper Marans would produce Blue, Black, or Splash Birchen chicks.

Is the chick completely White? Or is there some other color on the back?

How many toes does this chick have?

I think that it is the blue copper maran hiding the white color gene

I think that it is the blue copper maran hiding the white color gene

There's two white genes, Dominant White(Shows with 1-2 copies), & Recessive White(Needs both parents with a copy to express).

Then there's Silver, a different gene that makes white birds.
