Life's a Dream
I'm aware of what happened, but she doesn't talk about it at all. And I read the first light novel and in it she mentions that she doesn't even remember having a giant egg and it must be her imagination even thinking about it in the first place.Are you a manga reader or something?
It doesn't vanish in the anime, those human adventurers set fire to her web and she had to leave the dragon egg behind to run for her life.
