RIR or Splash Cochinwith Black Amauracana??

[77horses]

Hi!
We are planning on putting a black Amauracana pullet with either our RIR rooster and red star girls, or our buff girls and their rooster, the Splash Cochin boy. Both roosters are nice to the hens and have great manners, but I was wondering what the eggs would turn out to look like....? She will soon be laying normal blue eggs, unless we mix her with one of the roosters......
Someone told me that if you put her with the RIR she will lay green, pink, or yellow eggs. Is this true with all breeds? Will her eggs be dif color if she is with the splash cochin???
Thanks!

The rooster has nothing to do with what color egg a hen or pullet will lay. It is already encoded in their genetics.

Now, the offspring's egg color will change depending on what genes are crossed together.
