Definately not running together. Each variety consists of a roo with anywhere from 2-4 hens of the same variety.The only ones "crossed" are the ones labeled as such.My project pens.I usually do not sell any of my project eggs as I've been hatching for myself,but I figured I would offer a few if interested. If you would like just let me know with/without projects. All eggs are marked as picked,so no mixups(unless hubby decides to help out...lol.But I think I've got him trained...lol)

Is this true chocolate or dun?

I have to say true Chocolates,as Dun is more of a fawn colored bird and these girls are dark chocolate colored.I looked to see if I had any pics on my comp,but I don't.

The only breed in the US that I know of that has true chocolate is the serama. OEGB are dun. One way to tell (Whiskey Bay) is by how it expresses. If you cross a 'chocolate' bird to a black bird, what color are the chicks? If it is true chocolate, all the female chicks would be chocolate and all the males would be black. Dun works like blue, different 'shades' depending on how many 'doses' of the gene it has.

This is how two of my hens look and the only differences in the roos is my roo has some brassing in the wing and darker hackles.I also have one hen that is a choc splash version.I admit I am no genetic scientist,so when it come to the "genes" I'm clueless.However I am getting chocolate bitties from almost every egg hatched.I've gotten one cockerel almost black with some brass leaking into the wing.I have not crossed the hens over a black bird.

If you breed chocolate to chocolate all chicks will be chocolate. According to Chris09, breeding dun to dun gives you dun splash (25%), dark brown (50%) and black (25%) (https://www.backyardchickens.com/forum/viewtopic.php?id=389206)

Dun: There is another allele on the Dominant White gene/locus called Dun. It is recessive to Dominant White but (semi-)dominant to the other alleles. Two copies of the allele render a Khaki color, also called Dun Splash for it can be very white. It is also a clean kind of white, no specks. Darkened by melanizers it gives a nice light brownish lavender tint. One copy of the allele gives a chocolate color instead of black. This is a nice even color ranging from brownish gray to near black chocolate color (probably due to melanizers). No black spots like splash Blue can have. Dun is not very common in some continents, as is Chocolate. Both mutations are often missed or seen as off black.
Chocolate: Chocolate is a sex linked recessive mutation with a similar appearance as heterozygous Dun. The chick down seems darker though. In a recent visit to the dutch Serama empire there was a pullet harbouring both Dun and Chocolate. She was a lighter but prominent brown. Sexlinked brown dilution is the most common eumelanin dilution among birds and poultry, but still very rare in chickens.

Personally I like the duns, I just have enough OEGB colors as it is

Lol...Not being 'like that'....just decided if it seemed like an issue I'd withdraw the birds in question....lol..
