you are more likely to get some black and some white. you may get some splashes but i know with some breeds like silkies and rosecombs, black and white make blue and blue with splashes with other blacks and whites.
do it and see what you get! let us know how the chicks look!
I'm not a genetics expert but I believe if the roo is dominant white you'll get all white chicks if it's recessive you'll get black ones. That is if the black or white aren't hiding any other genes.
Sorry don't know - some of these genetics experts will chime in and tell you what to expect!! Good luck- If the colors don't come out as you like - I'm sure they'll still be great broodies!!
I don't know about the roo, because I just got him. He has WONDERFUL confirmation and I thought I could add "fullness" to my chicks. My hens have always produced black chicks, but I had a black roo.
I never had any unexpected colors from my hens.
Thanks guys for all of the input. I will just have to wait patiently and see what hatchs
