fast way to level up hatched mons?

Raise affection to rank two by petting them and giving them beans, take them to the highest level pokemon you can find, preferably a trainer, switch them out, win the battle, and they get thousands of EXP.

I always grind at the area next to Poni Meadows, i think it was called Poni Plains. not sure tho.

Combine these two, that's the best you're going to get.

Feeding them a rainbow bean is the easiest way to get the needed affection.
Also for mons that evolve at a fixed level, hold off on evolving them as much as possible, mons level up faster if they can evolve but haven't.
Not OP but these posts were really helpful, thanks.

I just leave my pokémon in the hotspring overnight.
