Fawn silver duckwing?
They have the wild type duckwing gene, the silver gene, and one dun allele (and one black allele.)
Two black alleles produces black, one dun and one black produces fawn/dun, and two dun alleles produces khaki.
Fawn silver duckwing bred to fawn silver duckwing produces half fawn silver duckwing chicks, but also some silver duckwing and some khaki silver duckwing.
