Guido99: these Dragons are called Golden Hybrids because the Egg, while being almost identical to the regular Egg of the hybrid composed of the same elements, contain a golden part. Sometimes it's the primary element, sometimes the secondary.

Pretty soon after the first five where introduced someone on the Wiki coined this phrase in one of the comments. It stuck.

When you visit the Eggs Page these Eggs can be easily viewed. Of course the Egg of the Bramble Dragon shouldn't have been included: this is, by definition, not a Golden Hybrid.
