you need to get a bird with the genes for the variety you want.
greywing and clearwing and dilute are recessive varieties that are related. a greywing can carry the clearwing or the dilute gene, so sometimes you get them from a greywing. you need parents that carry these genes to breed more of them.
clearflight pied is a dominant variety. to breed one you need at least one parent to be a clearflight.
