A Mixed Chicken ... Who Knew?

[Mimi13]

My question is, how could this have happened?

I sold a friend 4 hens and a month later I sold him 8 fertile eggs for one of the girls that had gone broody. Even though my hens are all purebred, my rooster is not. He a beautiful mix of a Welsummer over a Barred Rock.

Rusty has produced many beautiful offspring, but they have all been very colorful, lots of red and gold from his Welsummer lineage. But much to my surprise, I was literally shocked to see his offspring that hatched from one of my eggs that I sold. The mother is a White Plymouth Rock. She has hatched out several other birds for me and they have all had a certain orange and white coloration, hence their names of Peaches N Cream and Tater Tot, you get the coloring idea. However this particular one BLEW MY MIND!

Without further ado, here is the beauty!

I know these aren’t the best pictures, but how in the world would this cockerel have turned out 99% white? I think I see tinges of yellowing in his hackles, but is he not gorgeous? I’m still shocked!

You said the mother is a White Plymouth Rock. He must've gotten his coloring from her.

But I wouldn’t think white would be dominant over the sharp colors of red and gold of a welsummer.

You're right. But that's the only thing I could think of.

Recessive white, perhaps? You'd have to test breed to confirm, but it would behave like that. It only shows up on chickens with two copies of the gene, but when it does, it completely whites out whatever other colours the chicken has.

Edit: looked it up and yep, that's the white that WPR have.

That is very interesting and shows how little I do know about genetics. I’d maybe have learned more in high school Bio if they had used animals I was interested in. Eh, probably not.

Recessive/dominant white is a particularly cool one! If you bred him with another recessive white chicken, they'd only have white chicks, even though it's possible none of the grandparents were white.

But breeding him with a dominant white bird could easily result in zero pure white chicks, although white with leakage would be pretty common.

Dominate white: I/I, I/i+___Will leave Color Leakage.

Recessive White: c/c, one copy won't show. ___ C+/c
Dominate White has no color leakage.

Okay, I am so confused! @Kiraeh and @MysteryChicken, which do you suspect my White Rock is, I/I, I/i, c/c, etc.? These are the four offspring that have hatched from her:

From purebred Welsummer - both girls hatched January 2019.

From mixed Welsummer/Barred Rock roo — both birds hatched April 2020.

The girls are dominant white, & it's actually possible for the parents of the birds to carry both dominant white, & recessive white genes.

If the cockerel has any leakage, he's most likely dominant white also. I can't tell from the photo of him though.
