Cochin Bantam Cross: Black with Black Mtd

[joaomribeiro]

Hello guys.

I have 2 questions regarding crossing colours of Cochin bantam.

1 - If I cross a male Black with hens Black Mottled, what will I have? Will I lose the Mottled?

2 - If I cross a male Black with hens Blue Mottled, what will I have?

Thanks in advance!

Mottling is recessive, so yes, first generation cross to another variety without the mottling gene will lose the mottling outwardly. All chicks will carry the gene, however.

Black crossed to Black Mottled will get you Black chicks carrying the mottling gene.

Black crossed to Blue mottled will get you half Black chicks and half Blue chicks, all carrying the mottling gene.

Many thanks mate!

Final question from me: my first generation won’t be mottled. How can I have Mottled in the second generation? Which birds should I cross from the first generation/initial parents?

Thank you

No problem at all! As for getting mottling back from those chicks carrying the gene, you have two means of doing so. You can cross two of the birds carrying the mottled gene together, and about 1 in 4 of their chicks would be mottled. Or, you could cross the mottled-carrying birds back to their mottled parent (or to an unrelated mottled bird, for that matter), and about half of the chicks from that cross would be mottled.

Understood!
So, in short, to not lose the mottled what I should do is always cross mottled with mottled to have 100% chicks right?

Yes, that's the only way to guarantee mottled chicks.

Yes, that's the only way to guarantee mottled chicks.

And all of the above is valid either if you use a male black+female Mottled or female black + male Mottled right?

Correct, the gene is not sexlinked so inherits the same way regardless of which parent is the mottled one.

1000 thanks mate!

Howdy! I am Linda Frank in Tomball TEXAS. I am looking g for a Cochin Rooster that is nice. I have been through 3 roosters now. I had the cutest Cochin rooster named Clyde and he died of Diphtheria Pox. I just got rid of the meanest rooster on the planet and am looking for a rooster to watch my 5 hens while they play free range. And I don’t like being attacked so that’s why I would LOVE a Cochin like my Dear Clyde. Thanks! 281-630-2941
