You can go to Veilstone City and take your Chansey for a massage there. When its happiness is full, it will evolve by its ownself. Hope I helped.
Level it up when it its happiness is full
I think with full happiness (then level it up one level)It needs to have max Happiness AND you need to have the National Dex.
Go to the Pokemon cente in eterna and talk to the lady with brown hair and she will give you the happiness app (the one with all your Pokemon floating around and bumping into each other). Hold your stylus on apokemon of your choice and if 2 big hearts come out of it, its happiness is near if not full.
when you talk to it if it has six hearts around it that means its at max happiness
