Chocolate Birds in the US?

[Henk69]

There is the "dun" based chocolate that you refer to and there is a sexlinked recessive/purebreeding chocolate.

Not really like blue.

Blue is an incomplete dominant which is a diluter of black but not red. It is not sexlinked and it must be present in only one dose to show as blue, otherwise in 2 doses it shows as splash.


scroll up a few posts for the explanations on Choc.

SUMMARY


So then?

Is it the consensus that there are only dun based chocolates in the US, and that noone has any birds with the choc gene that breed true?

I think Henk said there are choc seramas in US. I doubt they're generally available though.

 

[Sonoran Silkies]

Seems like there was another breed with choc here. Have to look through posts...

 

[flyingmonkeypoop]

Didn't Sigi get the choc. gened serama from the US?

 

[Henk69]

Yes, she did.

 

[Rootball]

Okay so Sigi got the Chocolate seramas from the US.

Did the mutation arise on its own or was it introduced to those birds?

Serama seems like a weird breed to introduce a color to?

Anyone know the history of this.


Edited to Add:

While we are at it, here is a link to a choc disscussion at the Classroom at the Coop .

It states that Clive Carefoot(the original Chocolate orp guy) first observed the gene in 1994.

The chocolate mutation or the sexlinked brown mutation is one of the most occuring in other birds species!
It will have been there since centuries and will have popped up now and then all over the planet. But people tend to ignore. It is not a good black etcetera...

I found the dun mutation by coincedence on a poultry market. It looked like blue to me...

Don't underestimate the desinterest of people in their poultry plumage color. We are the lucky few.

My advice: keep your eyes open for off blacks.

Just kidding, but the Female mammal urine did have me thinking.
