Cochin rooster ?

[KellyAndMark]

We think this guy is a cochin maybe a bantam cochin ?
Is this standard colouring or is he a mix ??
We have been breeding him with our buff cochin bantam, excited to see how the chicks turn out !
Thanks !

He's so pretty! Delightful! I'd guess mix. Maybe Barred with Mottled?? His grandkids, mixed with the Buff could produce some golden barred chicks, but many of this generation (probably most) will probably be black and white barred! If it is mottling that he is carrying, it won't show up again until the grandkids ... at least that's how these things usually work. (Generally, Black (E/E) is usally dominant over Buff (eb or e^Wh) and Mottling is a recessive gene. Barring is dominant over everything, but is sex-linked.)

Good explanations...I am learning about the genetics and that is all good to know. One query, clarification? Barring will only be sex linked if the female is barred and the male unbarred. If the male is barred, all the chicks will be barred. As you continue to breed those chicks through further generations, the barring will begin to change and drop as the genetics mix. Am I correct @Spangled ?

Pretty boy. I will be fun to see how the chicks develop with your Buff Cochin. The gold does tend to crop up in generations, as my Buff Cochin with Mille Fleur roo's products show...a mix of black and gold and spots.

...and since the OP's roo is a mix of barred and mottled...doesn't that mean he will have only 1 barring gene? That will make the first generation offspring with some barred and some not?

Just curious...always trying to learn more from those who've had some experience with the outcomes of breeding.

Yeah cochin, probably the result of a cross between barred cochin with a mottled cochin. So a mixed color not standard on that rooster.

He is not pure for barred as there are some solid black feathers.

As for likely adult color on chicks out of him and buff hen- check out black sex links. Basically mostly black with variable amount of brown coloring on neck, breast and also on saddles for the roosters.

Half of the chicks in both sexes, will have barring, other half won't.

I agree if you let the cross chicks breed with each other, there will be extremely variable colors and patterns in their offspring. Buff mottled, buff barred, buff mottle-barred, regular buff(most probably would show some black on tails though), barreds, barreds with some brown color showing, mottles, mottles with some brown color, blacks, blacks with some brown......

Thank you for clarifying...I thought the 1st generation would have barring and non-barring as he doesn't have full barring but mottled/barred....always good to learn more about the genetics.

It's my understanding that Barring is always sex-linked. The genetic term B for Barring is a sex-linked trait.

You can used Barred chickens to make Sex-linked chicks. It is because B Barring is a sex-linked trait that B Barring can be used to make sex-link chicks.

In my initial explanation I was not speaking of making sex-linked chicks. I was commenting that only some chicks will be Barred when the rooster mates with the Buff hen and subsequent grandchildren (for lack of better term, like F2 or whatever it is). I wasn't commenting about sexlink chicks, which can also be made by using Silver, which is also a sex-linked genetic trait S for Silver.

If the above rooster is B/b+ instead of B/B, then the first generation babies will be 1/2 Barred and 1/2 Solids. If any of the chicks are golden, then that will prove that one of the original rooster's parents was not Black.

When I want to figure out Barring in crosses, I go to Henk's chicken calculator; otherwise, my eyes start to cross and I get a headache.

But I wasn't speaking of Sex-links, like when you go to the farm store and order Sexlinks (chicks). And those chicks are called Sexlinks because they were able to be sexed at hatch because of their breeding which included sex-linked traits Silver or Barring.

That's how I understand it. Maybe I don't understand it, but that's how my brain makes sense of it.

Right and you were right about non barred male over barred female- sex linked chicks. Forgot to add that in my previous reply...

and also for explanation on checking out black sex links for adult color- they are rhode island red bred with barred rocks, which is essentially the same thing as this cochin rooster and buff hens. Black is dominant but crosses with colored chickens normally give leaky colored chickens.

Yes....but the silver and the barring have to be on the female's side to create sex linking as it is the mother who determines the gender of the chicks in the chicken world (opposite to the mammal world)...so her genetics linked to sex (the W gene if I understand it...ooops would be the Z gene? as that is passed to the roo?) are passed to the males to produce those traits in the males...the hen has ZW while the male is ZZ

So a barred hen will pass barring to the males only, as the W is connected to the barring traits. Same with the Silver factor.

My understanding.

He looks like a bantam Cochin, but he isn't a particular variety.
