several questions on genetics

[Sonoran Silkies]

I am sorry about this, but I am still confused. I admit that I am not very smart when it comes to this, and I really want to understand, but I don't. It has to be broken down in laymens terms to me. For instance: If I cross a Blue Andalusian rooster with say an EE hen what color would that produce? What color would the egg be? If I cross a black EE rooster with a Blue Andalusian hen what color would the off spring be? If I cross a Black Copper Marans rooster with an EE hen what color would the egg be. I am really sorry that I am being difficult on this I just do not understand the genetics, or even know what chickens have what genes. I know that roosters have two z chromisones(sp), if that is even right. Thanks again for being patient, and not telling me I am stupid.

PS
I want to get an olive green egg, and I want to get BLRW. So I just need to know what to breed to what.

If only it were that easy

By EE, do you mean Easter Egger? Crossing an easter Egger to anything is a gamble--they are a mutt chicken; they may be beautiful; personable; lay beautiful eggs, but they are a cross, and without knowing their genetic makeup, trying to predict the results of a cross is pretty near impossible. Kind of like taking a known recipe and adding a can from your cupboard that lost its label--the results are unpredictable. You can make some guesses based upon what you DO know. If the Easter Egger is already laying, what colour are her eggs? Since Andalusians lay white/creamy eggs, their colour won't affect the EE's colour much--it may clean it up a bit (or not).

Black X blue will give you half blue and half black chicks, regardless of breed.

I haven't got a clue on the genes for black copper, but marans lay a dark egg, so paired with a blue or green egg it may well be olive.​

When you guys say black x blue, you don't mean the color of the feathers do you? For instance a black chicken x blue chicken. You are talking genes right. If so, how do I know if said chicken has black genes or blue genes? What breeds carry a blue gene, what breeds carry a black gene, mottled gene, splash gene. Am I making since.

LOL yes they mean a Blue chicken and a Black chicken.

Pick chickens.

Look for O - for Orpingtons

Or P, for Plymouth Rocks

Or C for Cochins

And then LOOK at all the colors - including yes, blue, black, splash, white, and so on.

Lavendar should be on the Orp list - if not search BYC for them there are plenty of pics. Or Blue Orps. Several people here have GREAT blue and lavendar (self-blue) orps.

Halo here has Blue Rocks - I want some.

Welcome to the wonderful world of chicken colors.

A black chicken should look black. A blue chicken should look blue. However, some blues are so dark that it can be difficult to tell.

If you get a copy of the standard, it will tell you which varities (colours) are accepted for each recognised breed. There should be chickens in those breeds with the necessary alleles to create those varieties.

However not every one of those birds has all the genes for all the varieties. For example, a blue will not have the mottled allele; because mottled is dominant, so it would show. A black does not have blue. Instead, these birds have the "not-blue" and "not-mottled" alleles, respectively.​

That would be good. Where can I get a copy of that?

I have a question along this same line. I think I read on here that breeding a white to a black can produce blue offspring.

If I breed my white rooster to my black australorp or jersey giant is there a possibility that I will get a blue chick?

What about a black roo over a mottled hen?

Only if the white is dominant white and is covering up the blue gene, other than that, you will not get blue offspring.

If the black is not carrying mo then all will be black with white specks here and there (mismarked).

Are you saying that mo has a limited expression when het? (Sorry to hijack the thread, but it sounds like exactly what I;ve been wondering in my own flock.)
