Color Breeding Qestions! HELP!

[Sonoran Silkies]

I guess that I'm at the level where knowing which of the various "helper genes" extend or remove colour from what areas of the body would be helpful. And I do realize from reading as many of the genetics discussions as I can find that not all is known about many of them; some are even not proven. But knowing specifically what Co, Db, Ml, Cha, etc. do would be helpful to me.

I am very poor at languages and have no trouble understanding the chicken calculator. I've learned a LOT just by playing around with it.

Kazjaps belgian bantam website has lots of information on breeding the various tri-coloured varieties (such as mille fleur, blue mille fleur, etc.) Unfortunately the site has moved and I don't have a new URL.

All chickens have all genes. If an particular allele for a gene is not commonly present in a breed, then it has to be introduced with crossbreeding to a breed that is known to have that allele by a bird whose variety pretty much ensures that it is present in the bird. Depending on the particular allele and its dominance relationship with other alleles for the gene, you may have to breed several generations. Or one may be sufficient.

Anyone interested in poultry colour genetics should have a look at chickencolour.com click on the book ,then 'take a look'.
Will be available in the US shortly

I've been eagerly awaiting the hard copy English version--any idea how soon it will be available?

I got the same results with Khaki, Black and Fawn coloring. Very interesting! Except my fawn colored ones were black laced

Even though they're not hen-feathered

Well, I've pretty much got the BBS colors down like Katie does. And in my D'uccles, Mille fleur X Self Blue=Porcelain.

Sorry about that, I was a little offended at the time, as I am with "Barely english"...

Normally mille * self blue should not give porcelains right away.

 

[Sonoran Silkies]

Yes, porcelain requires lavender (self-blue), which is recessive, so unless the mille fleur carries lavender the F1 offspring won't be porcelain. but will all carry a copy of lav.

So if the Millie doesn't carry the lavender gene, you'll get 50 Millie and 50 self blue?

Okay, I just re-read. The self-blue needs to carry mo and the mille fleur needs to carry lav to get porcelain offspring. Both lav and mo are recessive genes--to exhibit the trait, a bird needs to inherit from both parents.

Try setting up the chicken calculator with a self-blue (lavender) parent and a mille fleur parent. Manipulate their genes so that they each carry a copy of the recessive gene they need, then so that only one does, then only the other does, then neither does...and compare the crossing calculation results from each.
