Calling all chicken geneticists!

I’ve hatched chicks many times before, but not ever with my barred rock roo. I’ve got quite the mixture of hens in my backyard flock, including isa browns, rir, EE, and one silkie/EE cross. I’ve hatched two batches of chicks from this bunch recently, getting all black or gray chicks with the little white spot on their heads from barred genes. However, a little one hatched the other day that is pure yellow!! I’m shocked and confused as to how this happened! Anyone know why this little chick looks so different from the rest? Thanks!

What are all the breeds in your flock?

My rooster is a barred rock. I have two Rhode Island Reds, two ISA Browns, two Easter Eggers, an Australorp, and one silkie/Easter Egger mix.

Do you have any pictures of the EEs and the EE/silkie?

It's from the ISA Brown, they have one copy of dominant white

That’s most likely, though if one of the EEs has dominant white and doesn’t have a beard then she could also possibly be the parent.

I am going with the most possible answer here, we all know that EEs have all sort of colors due to them being crosses and not held to a standard.

It hatched from a brown egg, similar to what my ISAs lay. I hadn’t realized they have a dominant white gene! Very cool. Thanks for your responses!
