Genetics how did this happen?

[Rose Quartz]

I have barred rocks which the person i bought the eggs from had their BR'a in a coop and run not mingling with others.

3 marans mixes all black hens one with red neck markings.

And my rooster is a blue wheaton americana, or possibly a blue wheaton americana over a splash isbar.

I can tell the eggs of my marans mixes from my BR eggs. And this yellow chick with a black head spot hatched from an egg from one of my barred rocks. The day i gathered it i was sure enough which hen it was from i wrote her name on it.


Is this possibly a splash chick, and maybe my BR is actually a blue base, or is it possible the wheaton is changing the down color? I dont know anything about wheaton genetics.

Very interesting! Maybe once the chick fluffs up you could post some additional photos. To me it looks like it has one copy of dominant white. Which allows for spots like that. But it probably isn’t dominant white because you would definitely know if you had a dominant white bird.

I have absolutely no idea how you would get that chick from your flock. Maybe someone else will be able to figure it out! Very cute though!

Could it be recessive white? I thought I had read that white Plymouth rocks were a sport from barred rocks, which would make them recessive white. But if I did it was years ago and I don't actually know the genetics of white rocks for sure so I could be making that up.

It's possible. Thinking back to the hens she had with her americauna roo when i bought the eggs for my flock last year, i think her 'blue wheaton' hen may have been white with gold leakage. I had googled pictures and assumed that she was a blue wheaton because she was at a distance when i was there and that's what she said her hen was.

All fluffed, the other light chicks are from my moms eggs, they're red with stripes.

Okay yes, not dominant white for sure! I’d bet recessive white! I had some questionable chicks this past year that turned out to be recessive white (at the time I didn’t have any white chickens so I was confused.) It’s crazy how it can pop up!!

Good to know that hen is carrying it, and probably the rest of the BR are too. I bought quite a few new breeds with white this time for hatching so I'll have to be careful about who's who.

That would mean the rooster would also have to be carrying recessive white.

Judging by the rooster's comb, I think he is probably a cross, not a purebred blue wheaten Ameraucana. So he's probably got some hidden genetics.

Honestly, the chick looks very much like a wheaten chick. Who knows? Update us on what the chick looks like as it feathers out. It is an interesting case.

I think there's wheaten in play and not recessive white myself.
Recessive white covers everything so I wouldn't expect that black on it's head.
The recessive white chicks I've had were never the bright yellow either. Most were closer to white with a grey tinge
