Sorry, yes, I've figured it out now. Apparently he has a cock bird who carries it and keeps throwing chocolate pullets. I'm talking to him now and he thinks he knows which one it is. So he's going to put that male with his chocolate females so he can get some more males

Yes, you are correct...I'm glad my mistake was caught so we can clear things up!

OK, this is my understanding of the chocolate gene, after doing some more research...
****************
The sex-linked recessive gene named “Chocolate” by the late Dr. Carefoot in 1995 is another dilution of Black pigment. The Chocolate gene is one of the few known sex-linked recessive genes in poultry. It may seem difficult to grasp at first, but if a female carries Chocolate, than she will be visually Chocolate. However, males require two copies of the gene for them to appear as Chocolate. Black males can carry a copy of Chocolate without it being at all identifiable. The only way to tell is to test mate. However, if the mother of the Black male in question was Chocolate herself, it is a certainty that all her sons will carry a single dose of the Chocolate gene. According to Sigrid van Dort, in her book on Serama Colours, the rooster needs 2 doses to show the color chocolate, while the pullets need only one dose.

Chocolate to Chocolate gives: 100% Chocolate offspring.

A Chocolate male to a Black female gives: 50% Chocolate females, 50% Black males (the males will all carry Chocolate). This is what I've been working on.

A Black male to Chocolate females gives: 50% Black males (Chocolate carriers) and 50% Black females (normal Black and does not carry the chocolate gene).

A Chocolate carrying male to a Black female gives: 25% Chocolate females, 25% Black females, 25% Chocolate carrying males, 25% Black males – though it will be impossible to tell which males carry Chocolate.

A Chocolate carrying male bred to a Chocolate female gives: 25% Black females, 25% Chocolate females, 25% Chocolate males, 25% Chocolate carrying males (Black).

Shelley-

This is what Sig has to say about chocolate hens in a post on SCNA (http://www.scnaonline.org/scnaforums/index.php?showtopic=3787&hl=)...

"Working with a black rooster of at least 2 years old helps, but this will take another extra year to have a choc rooster (black rooster x choc hen gives no choc daughters and all split (black) sons) since its sex linked recessive."

So, if she is correct, how can a chocolate hen produce chocolate pullets from a not-chocolate rooster? Either she is dun, or the roos are actually splits, but she would still be producing black pullets as well...

Is this not correct?

Whew! Complicated stuff!

Okay, we finally have it straightened out...I think!!!

This should probably be read as (pullets): 50% chocolate and 50% black; or (cockerels) 50% black split for chocolate and 50% black.

A Chocolate carrying male bred to a Chocolate female gives: 25% Black females, 25% Chocolate females, 25% Chocolate males, 25% Chocolate carrying males (Black).

And again, it should probably read (pullets): 50% black and 50% chocolate; or (cockerels) 50% chocolate and 50% black split for chocolate. There are no guarantees that you will get 50/50 males and females in a hatch, so I think this is more understandable.

As for your other comment, if you noticed I went back and edited my post. No need to bring it up anymore

These statistics are equivalent. The only difference is whether the percentage is out of all the offspring or if you break it down between males and females. However you slice it, your total sample can never add up to more than 100%.​

Shelley-and Henk69, too

I've got a question for you...What do you get if you cross a chocolate male to a non-chocolate, buff colored female? Is the chocolate gene carried by any of the offspring???​

All offspring will have the sex-linked choc gene. Males will be carriers, females will express it as exhibiting chocolate in areas that would otherwise be black. Depending on the genetic makeup of the parents, you could have nearly solid choc females, or choc-tailed buffs, or some other mystery color/pattern. It all depends.
