Color genetics thread.

Hi,
I am interested in the genetics behind this ≈12 week pullet (mille fleur d'uccle x cross breed hen), can anybody help out? Could it all just be leakage on the breast? Could it be related to the columbian gene?

Hello again everyone! I was wondering if anyone knows what breeds or varieties have the Cb gene (champagne blond). It's a dominant diluter of gold. I believe it only dilutes feathers.

(I was thinking the flarry eye grey birds at greenfire farms carried this gene but I'm not so sure since their shanks are cream.)

Hello everyone! I'd like to ask if anyone can explain my hen Mykerion's color to me.

So years ago, two of my bantams had a baby.

The father was a reddish-brown Cochin bantam.

The mother was a black Rosecomb bantam. (She is young in this photo, never had a good adult photo of her, but she grew the proper Rosecomb white earlobes and comb type.)

As far as I know, these birds were both purebred. They came from the mixed bantam bin at TSC when they were chicks.

When grown, Mykerion (their daughter) turned out to look mostly like her mom, but with red neck feathers!

I didn't realize until I got a standard black sex-link hen earlier this year (who looks like a massive Mykerion) that the black-with-red-neck is, well, a sex-linked color. But it's my understanding that in the sex-link breed, you get that color by crossing a reddish rooster with a black and white barred hen. Mykerion's father was reddish, but her mother was definitely not barred at all.

So how'd Mykerion's color happen?

She is basically the same color/pattern as a female black sex link.
You're correct a lot of BSL use a red rooster as you did. Pretty much same genes from fathers side.
With BSL the female is barred which is passed to her sons but not her daughters so males are barred and females aren't. Hence the sex link.
In your case you used a black female. Barred is black with barring so your cross results in producing the same female chicks. You just left out the barring which would of resulted in males being barred.
Make sense?

Makes perfect sense! Thanks!!

Any ideas on the genotype of this cockerel?

I have this pullet. I'm not sure what the color is called but I would like to produce more colored like her. What color male would be best to use? I'm not particular as to the breed just so it is large fowl. Thank you.

I’ve got a color question, I’m trying to get some white chickens.

So I bred this rooster, Stonefrost, (his dad is buff Brahma bantam, mom barred Cochin Bantam) to my white Bantam Cochin hen Marshmallow

They produced this little guy, Darkfrost.

And his two sisters, one has gold leakage the other has silver.

And those three have a half sister (Ninja) who is black with gold leakage also, they have the same white Cochin mom, but her dad was a blue Cochin.

My question is what hen is the best way to get white chicks? Who should I breed Darkfrost to? I have a different white Cochin hen (snowflake) that I could use.
Would Darkfrost x Snowflake get the most white chicks?
Is breeding him with his sisters a bad idea? What about his half sister, Ninja?

I've seen several of your posts in the past and can't agree with who you believe are the parents of some so with that and the extreme mixture of color/pattern genes you have going on the outcome of most would be too far mixed to have a clue.
That said your white Cochin is recessive white. Every offspring from her will carry one recessive white gene. Breed a son of hers back to her and you should get about 50% white chicks.
Breed any of her offspring together and you'd average 25% white offspring.

There are 22 week olds, and 11 week olds.

the roosters with red leakage are beautiful.
