Chocolate Birds in the US?
- Thread starter Rootball
- Start date
The chocolate gene in the Orpingtons in England are sex linked. It is not a dilute/double dilute deal like blue and dun. You either have it, (in the males) or you don't. If the male is black, it does NOT carry chocolate unless his mother was chocolate. If his mother was chocolate, he is guaranteed to carry it.
If a black hen had a father that was chocolate, she will for SURE carry it, and only pass it on (visually) to her male offspring. I believe half of her female offspring will not show it but they will also carry it and pass it on visually to their male offspring, and will have a fifty fifty chance of chocolate genes passing on to each of their female offspring.
If you breed a chocolate roo to a chocolate hen, everything will be visually chocolate, with the sex linked chocolate orpington gene anyway.
Edit, OOPS! Second half of the first statement is wrong. If the rooster is black, he does NOT carry it!!! This part of my statement is NOT TRUE! Please ignore!!!
"If the male is black, it does NOT carry chocolate unless his mother was chocolate. If his mother was chocolate, he is guaranteed to carry it. "
The truth is, if his mother carried chocolate, he would BE chocolate. Black males cannot "carry" chocolate! Sorry for my mistake.

Yeah thanks OTS! I had read a bit about the choc gene in Grant Brereton's Book, but I wasnt able to put it as succinctly as you at this moment. I guess I m wondering if this gene is available anywhere in the US.
Here is a link to some British Chocolate Orpingtons . The Chirpy Chicks site sells hatching eggs and breeding trios.........to the Welsh.

Chocolate male to black female ought to give chocolate female offspring & black male offspring carrying a choc gene.
Black male to chocolate female ought to give all black offspring with all males (biut not the females) carrying one chocolate gene.
Both parents chocolate ought to give all chocolate offspring.

You have it partially correct, but partially incorrect. Yes, choc is a sex-linked recessive gene. However, for sex-linked genes, males have two copies of each gene locus and females only one.
A hen either has it or not. She only carries one copy of the gene. If she carries choc, she will be chocolate coloured and pass the gene to all her sons. If she carries Choc+ (not-chocolate), she will not be chocolate coloured and will pass the Choc+ version to her sons.
A male carries two copies of the gene. He can carry Choc+/Choc+, Choc+/choc or choc/choc. Only those that carry choc/choc will display the colour chocolate, and they will pass the gene to all their offspring, regardless of gender.
Those who carry Choc+/choc will not appear to be chocolate coloured, but will pass the choc version to approximately half their offspring, regardless of gender.
Those who carry Choc+/Choc+ will not be chocolate and will pass Choc+ to all their offspring.

Sonoran, why don't you use the + suffix for wildtype alleles?

What a mess!
A black son can carry chocolate (being Choc+//choc) that originated from his father too (his mother being black and donating black Choc+).
If his mother carried chocolate SHE would be chocolate (choc/-).
Only males can carry chocolate without showing it (Choc+//choc).

What would be the advantages of a chocolate bird? Camoflage? (sp?) Would any breeds actually look better?
