Cuckoo color?

[Simpson Farm]

Ok, here's my question about the cuckoo color. How do I get it or rather create it. I have seen polish and silkies in this color and I'm trying to create them. What would i breed to make them have the cuckoo color?

Cuckoo barring is dominant. Put a cuckoo roo of any breed on anything else, and you'll get barred offspring.
