Thank you so much for your explanation. That is very helpful.Do you want to test mate your fibromelanotic birds to see which ones are homozygous for the trait? If so, the reason you would want to use slate or willow legged birds is because they have the wild type leg color that won't interfere with your test matings. Birds with light legs (white or yellow) have a sex linked dominant gene called inhibitor of dermal melanin. This gene blocks dark pigment in the skin and legs to a large extent, especially in young birds. This will make it look like your potentially homozygous fibromelanotic bird isn't passing the gene onto all of his offspring even though he is.
