When I hatched the Togepi egg you get from Proffesor Elm in Pokemon SoulSilver, It had a Naive nature. I tried soft resetting to hatch the egg again, but no matter how many times I did it, it's nature was always Naive. Is it supposed to be that way?
I see your problem! Ok so when you receive an egg everything is determined from natures, IVs, and shininess. There's probably a bit more that's set but those are the ones I remember. So no there is no certain nature it's just when you receive an egg everything about it is determined when you get it.
