Well, in this short story, perhaps the main character is a simple farmer who accidentally finds the dragon egg in his field. There could also be a group of villagers who are initially afraid of the egg but later come to support the farmer in protecting it. And then there could be a dark sorcerer who hears about the egg and tries to use it for his own evil plans, making him a key antagonist in the story.
The main characters are the boy and the dragon that hatches from the egg.
I'm not sure as the information is not given. But usually in a short story, the main characters are the ones who drive the plot forward and are most involved with the central element, which in this case is the egg.
Since I don't have detailed knowledge of 'the egg short story', the main characters could be various. It could be a group of adventurers who stumble upon a mysterious egg during their travels. One of them might be the leader, another the curious one always asking questions about the egg, and there could be a cautious member who is worried about the consequences of dealing with the egg.
As I haven't read the 'the sacrificial egg short story', it's difficult to say. There could be a young child who discovers the significance of the sacrificial egg, or an elder in a village who is in charge of the ritual involving the egg. There might also be other characters who oppose the sacrifice of the egg, creating a conflict in the story.
I don't know as I haven't read it. Maybe there's a brave hero.
The main character is definitely the entity that is reborn as a dragon egg. This character experiences a complete transformation from its previous form (although we may not know what that was initially) into a dragon. Along the way, there could be other characters such as wise old dragons that act as mentors, or perhaps some humans or elves that cross paths with the newly hatched dragon. These secondary characters can either be friends who help the dragon understand the world better or enemies who see the dragon as a threat to their own existence or power.
I'm not entirely sure without more research, but typically in a story inspired by Bluebeard, there would be a male figure who has secrets, and a female figure who discovers or is involved with those secrets. So there might be a male and a female as main characters.
I'm not sure specifically as I haven't read the exact story. But it could be a scientist who discovers the special egg.
I'm not sure without more context. It could be a mother bird if it's a story about a bird laying and protecting an egg.
The protagonist who becomes the dragon is of course the central character. Then there might be other important characters such as elder dragons who could guide or oppose the main dragon. There could also be some human characters that interact with the dragon in different ways, like a wizard who tries to communicate with it or a knight who might see it as a threat.
