i dunno either...
I have seen blacks look like they have gold in hackles due to sheen
I've also seen some with gold in hackles that were pure Ameraucana but some trait somewhere back when threw gold. (the one I've seen had what I call split feather coloring. half black half dark red/golden color divided down the feather shank. my guess is a red or wheaten color bird was used at one time in the past?)
I would never use a bird with leakage for a breeder but it does happen.
