unexpected white chick - Lav Roo, White EE Hen

[tolmema]

I just hatched my June batch and had a surprise!

Roo is a Lavender Ameraucana.
I have 4 black hens (brown eggs) and a white hen (blue eggs).

The brown eggs hatched as black lavender splits just as expected.

Only one blue egg has hatched so far, but the chick is blonde/buff/cream color + a silver/lavender spot on its back. pink beak, clean pink legs. I can't tell if it's lavender? white? both? So now I'm trying to figure out more information about the white hen.

As I understand it, a Lav roo should always throw a black lav split with the exception of a barred hen, white-dominant hen, or a lav split/full lav hen.

this is the hen. no idea on breed, i assumed an EE of sorts. she is from the same flock as the rooster. so she may have lav recessive gene already. she has a few dark feathers on her back, on her wings, and around her neck. and mostly slate legs.

this is the rooster.

Most probably the Lavander roo is gold based, so he throws gold chicks with the white hen.

I think the white hen with spots has one dominant white gene that she passed on to her offspring. 1 dom white gene crossed with the black gene will give white birds with a few black spots, like her. That's my take, anyway.

thanks for your take. i found this article: https://scratchcradle.wordpress.com/2012/10/21/gms-supplement-1-recessive-white/

"Dominant white(I) is a gene related to dun and smoky (see below) which inhibits the black pigment eumelanin.1 Basically, it removes any black pigment and leaves the feathers white. It doesn’t affect the red pigment, phenomelanin. Birds which are heterozygous, carrying only one copy of dominant white (I/i+), tend to leak some black pigment which shows up as grey or speckles.2 White Leghorns have the dominant white gene.


(Dun (Id) dilutes the eumelanin to brown and two doses (Id/Id) dilute to khaki. As one or two doses produce a different effect, dun is incompletely dominant. Smoky (Is) is a recessive form which dilutes black to blue.3)"



Is it possible the white hen has the l/l^d white dom gene, which would produce white or dun/fawn colored chicks against a lavender roo? that's the only thing i've put into the chicken calculator that makes sense right now.

Update: The white hen is most likely an Austra White Ameraucana cross.

Austra Whites come from a black Australorp Roo & a white Leghorn Hen. So she has the white dominant gene and lays blue eggs.

Austra White chicks are white with some small black spots on them.

So this baby is an Austra White Ameraucana lavender split.

This chick is now 4 weeks old. I have never grown out a white chick so I'm unsure if it's white or lavender. It's mostly white/lav with some yellow/lemon/cream coloring on top of the wings. Head is still fuzzy yellow. Some black spots.

Did you ever fully figure out what color this chick is? I’m sure it inherited the dom white gene from the mom, but if the mom is also carrying lavender, then it could have lavender colored spots instead of black colored like the mom has. I would be interested in seeing an updated photo if you still have this chicken!

The community here says he's a paint with autosomal red. he didn't end up as a lav, but he is a lav split. i attached some pics to show how the khaki color turned out. he also has some true black tailfeathers now rather than just a couple little splotches here and there.

How crazy I was just asking on a post today what color my tan paint pullet is and was told she is most likely autosomal red over paint as well! Mine is a similar situation, a lavender ameraucana (bantam) dad and a paint mom. I’ll post the pic of my girl.

Your boy is so cute. I bet the color genetics are similar to my girl. Have you bred him or hatched any of his chicks?
