Shadow dragons aren't a species per se. They are the result of a dragon getting pulled into and changed by the shadowfell. There's a shadow dragon in one of the campaign books who used to be a black dragon, for instance.
Actually in 1e and 2nd edition they were a species its only til later versions did they expand on that. But regardless they were altered and after there DNA was altered as mutations from exposure to the shadowfell, and their offspring could carry genes to become one. so technically they are made by exposure to the Shadowfell, if two shadow dragons mated they would make shadow dragon offspring, reguardless what type of dragons the parents were before the mutations of the first dragons to become a shadow dragon in there blood line or themselves were prior to becoming one.
