It is not the presence or absence of silver/gold that causes off-colour in the hackles. These genes are ALWAYS present in every bird. Every female is either S/- or s+/-; every male is either S/S, S/s+ or s+/s+. You can have a perfectly coloured blue or black bird that is either silver or gold based, and shows no off colours in any portion of the plumage.
Off coloured hackles are caused by the presence of not-melanizer genes. Their alternate alleles (melanizers) extend the eumelanin (black pigment) into the hackle area. Additionally, autosomal red can and does add red pigment, especially on male shoulders and wings.
Completly lost. I need to do more research!!
