Blue genetics question

[Sonoran Silkies]

You can get white, black, blue, splash & various mixes, depending on how you choose to pen the birds.

White X anything else is unpredictable. If you want to see what you can get, breed them to a different colour, but don't expect the offspring to conform to a standard colour. They could, but chances are they won't. If you get any white chicks, the non-white parent has a copy of recessive white.

I think you said you understand the percentages of breeding splash, blue & black?

Interesting thread. I just hatched a blue chick out of a white EE hen and a RIR/Brown Red Game rooster. What a surprise that was! The other chick from this cross was black. I guess my white EE had a blue gene underneath that white feathered exterior.

The other white EE hen used with the same rooster produced all chipmunk or wild type chicks.

I know that. The parent birds aren't mine. I just got a bunch of different colors than I expected from a batch of shipped eggs, and I'm trying to understand.

I'm sorry. I didn't realise.
What will have happened is that when a white bird has bred with one of the other colours.
Two recessive white genes will stop any colour expressing, no matter what colour the chicken might have been without the genes. One recessive white gene does not stop colour so the other genes also carried by the white parent can then express in the chicks.​
