Is Golden Buff a hybrid like an Amber-link or something? I'm not familiar with that variety. I don't believe you'd be able to sex the chicks at hatch if that's what you were hoping for. In terms of color, I'd imagine the resulting chicks would be sort of a reddish gold color. I'd say "go try the chicken calculator" to find out the color but if you're dealing with both parents being hybrids I'm not sure how accurate a result you'd get.
