How do Dragons treat their young?
Dragon eggs are rarely left with the dragons themselves. It’s so rare that they hatch in the first place that they’re taken to safety soon after they’re discovered for fear of squashing/freezing/stealing.
Dragons usually aren’t very paternal creatures by nature, the only beings they truly form bonds with are their riders. But once the young dragons hatch and are taken back to live in the caves, it’s not unusual for the clutch parent to assume the role of “guardian”. Ie making sure they’re not eaten by other dragons.
Occasionally there while there will also be dragons like Bat, who are very tolerant of other dragons, especially young ones. And will allow them to nest with him. But that’s highly unusual.
