Ok, Where did you get your Orps from?
You may have to test breed them to see if they are True Chocolate or Dun hobby name "chocolate".

As for the hens in the picture you posted they could be a Dun Splash hobby name khaki.
If they are Dun Splash hens then you would breed Dun to Dun.
The Muave hens I have see have more lacing in them and are a Dun/ Blue Splash Cross
Last picture on this web page shows Muave http://www.orpingtonbantams.co.uk/choc.htm

Pic came from uk ebay http://www.ebay.co.uk/itm/6-x-Chocolate-Mauve-Laced-Orpington-LF-Hatching-Eggs-/160623644567?pt=UK_Pet_Supplies_Poultry&hash=item2565ea4f97

it says "Black cockerel split for chocolate (Carries the chocolate gene) and 4 Chocolate/Mauve Hens who also have the chocolate Gene"

I do not have my chocolates yet but they are coming sooner then later

A Chocolate Male X A Splash female = 50% Blue males recessively carrying Choc and 50% Mauve females (the color you want)

Breed those Mauve hens back to your Chocolate roo and you will end up with Chocolate and Mauve males and females.

Old thread, so you might have already figured this out yourself, but I figured I'd help...

mauve = sexlinked chocolate plus one dose of andalusian blue
platinum = one dose of dun (allele of dom.white) plus one dose of andalusian blue
khaki = 2 doses of dun

These 3 colors are very similar looking.

lavender is said to be epistatic to (=covering) both forms of chocolate and andalusian blue (the other blue). Also similar to the above.

When you say Dun is an allele of dom. white, what exactly does this mean? How is Dun related to White, if at all?

The way I understand Dun is that it "dilutes" Black, like Blue does. Is this incorrect? Is there a better way at explaining what it does?

Like dom White does it simply "mask" Black?

 

[Henk69]

Good question.

The so called dominant white gene in it's natural form does not make a white bird. The gene was discovered because a mutation of that gene had that effect.
The natural form and the changed/mutant forms of a gene are called alleles. Dun is another mutated form of the same gene.

Dominant white does not mask black because there is no blackness underneath. But it blocks the expression of black.
Dun does this too, but way less, especially in one dose.
Blue and dun are not diluters in the sense that they are some extra pigment that when mixed with black gives another appearance.
They act by decreasing the amount of black pigment and in the case of blue clumping it. In the pigeon when the pigment is "declumped" by the so called "Spread" mutation, the bird gets black.
Also the shape of the melanosomes (pigment containing vesicles in the cell) is often changed by these kind of mutations.
Other diluters block the transport of these melanosomes to the place where they are best seen.
The brown color of dun and chocolate is said to be a lower quality of eumelanin (black pigment), but is not necessarily chemically different.

This explanation is not very detailed. I am sure others will chime in...

Not sure how much genetic basics you understand or not. If not a lot, this analogy might help. Think of a gene as the residents at an address, and an allele as a member of the resident family. Now, if the gene is the Adams, then only a member of the Adams family can live there. And the Adams family might consist of Mr Adams and Mrs Adams. There is only room for one of them to be present at a time. Next door are the Bakers, consisting of Tom, Tommy, Ann and Lynn. Next the Cook family, and on and on down the street.

Now across the street, are an identical set of houses for the Adams, Bakers, etc., and once again, only one of the residents can be there at any given time. But, you can have two Mrs or two Mr Adams, one in each house.

Henk & Sonoran, thank you both for the explanations!

Hi, one more question........what about a chocolate sex linked hen to a splash cockerel? what about a blue hen to a black/split chocolate rooster? Still trying to figure out these genetics.
