1. What two Colors Make Chocolate?
2.What Two colors Make Blue?
I like to create a Blue or Chocolate chicken by Mix breeding.
1. chocolate and chocolate. khaki and black. chocolate and black.
2. blue and blue. splash and black. etc...
To create a color you need only one animal that carries the desired (mutated) gene. And an animal of opposite gender to breed with... ;)
The animal in my avatar carries both chocolate and blue. So with him you could make both colors.
