I think you would get something like some Cuckoo Silver Duckwing (Double Factored males) and possibly some CuckoosI bred a double factored cuckoo rooster to a silver duckwing female.
Then bred those offspring together.
This is one of what they produced.
Follow that?
Know what that pairing could produce?
There could be 4 different pullet patterns and 4 cockerel patterns.
