thanks dan, dominant white does dilute pheomelanin in homozygous form, Blue seems to fade pheomelanin even in heterozygous form, mahogany seems to counter this effects, my first cross to a self buff bird has yielded a Blue birchen bird that has almost white shanks even if his dad had Black ones, she does not seem to carry Id. seems you are correct in thinking that breeding to erradicate the genes that fades pheomelanin will take alot of effort..
