Cross Breeding Bantam Cochins of different Colors

I think I understand what you mean.

But the term "dominant black" in mammals is for another allele from the same gene as recessive red.
This gene has 3 forms now, including the new found "dominant black":
E^D = the dominant black allele.
E+ = the wildtype allele which is needed to express the agouti-based black.
e = the recessive red allele.

If not for the new E^D allele, the E+ allele was the prerequisite for expression of black in the horse's coat, hence it is often called "black".
And it IS dominant to recessive red.

Most black horses are E+/? at the extension gene and a/a at the agouti gene. Black is recessive to Bay.
A dominant black horse is E^D/? at the extension gene and can be anything at the agouti gene.

Sorry I dropped the ball here, I got side tracked by a serious cold snap that we are having and the need to address my birds combs, etc. Plus! I'm moving to my new forever home.
Henk, I must bow to your superior knowledge on the subject.

Obviously, I was operating with a laypersons knowledge of genetics, hopefully enough to accomplish what we were hoping to and not do any damage in the process.
I must say I did breed some very beautiful colorful Quarter Horses and as far as I know I don't think I created anything as horrible as HYPP.

Sick joke - sorry.
I have poultry genetics books specifically ordered, and I will begin reading the terminology and hopefully I'll do better at keeping up in the future.

I enjoy a more general discussion about genetics.
Very rare that people look beyond their animal group.
So opportunities like these are grasped.

Henk...you may see this on FB first but I am trying to find out if white in bantam Cochins is dom, rec, or just white as in the Chicken Calculator. I crossed a white frizzle Cochin bantam hen with a white Silkie roo. Should I expect all white chicks? I know frizzle, but need to know white. I am in the USA.
TY

What do you mean "just white... "
I guess it is rec.white. Once it was believed that silkies had their own kind of rec.white and in that case rec.white 1 X rec.white 2 would give colored offspring. But that is not the current belief.

If you are using the new chicken calculator, there are 3 options for thw color white. These are: white, recessive, and dominant white.

To get white you must breed white to white, and I would say after reading some of the more advanced breeding threads, for us beginners it's best to breed color to color, i.e., partridge to partridge, birchen to birchen. Things do get a little fuzzy with the black, blue, splash thing and if you understand it in ameraucanas then you understand it. It holds true in all breeds. A partridge to a white?, I haven't a clue, the blue to the red you start getting into a sort of muddling that has it's own problems. There are so many people working on projects, but they know a lot more than you or I do. I'm leaving it up to the other folks with more experience and room than I have. It sounds like you may have a partridge roo and a blue roo. If that is what you have, you might think about keeping the blue roo as I think he gives you more options than the partridge. I happen to have a soft spot for partridge, but there's just nothing else you can breed them to but a partridge hen.

Creating crosses of colors are fun. Infact cochin bantam is the breed partridge and birchen are just the color variations. And honestly it's fun to mix the colors because you get some pretty ones. Like rn I have a mottled roo over my buff, birchen, white, partridge and black hens. Last alternation was a birchen roo over them. It's so much fun. And let me tell you the birchen over buff were gorgeous.
