Delta Pichu/Pikachu Evolution

How do you evolve delta pichu and delta pikachu? I’m doing an egglocke (and currently getting absolutely destroyed) and I just hatched a level 36 delta pichu. I really need strong mons and a fairy ype would help me a lot. How do I get this evo?

Pichu evolves from happiness iirc and pikachu needs a shiny stone.
