Do you think the daycare REALLY doesn’t know where the eggs came from, or are they just saying that because they don’t wanna have to tell the protagonist about the Pidgeys and the Beedrills?
Unclear. In the original Gold and Silver, when eggs were introduced, a Pokémon egg was such a bizarre curiosity that Professor Elm was shocked and elated to be given the chance to study one, which suggests that the writers originally had in mind a world where most people honestly know almost nothing about Pokémon reproduction, but Heart Gold and Soul Silver seem to retcon that to some extent. And then there’s a guy in X and Y who tells the player that Pokémon eggs “aren’t really eggs,” which I suspect is Game Freak winking at us and saying “yeah, whatever you think you know about this is wrong.” I think there really is supposed to be a degree of mystery about how this stuff works even in-universe.
