How do you get egg moves on Chansey, seeing as you cannot breed?
Exactly what do you mean by "you cannot breed"? Chansey is part of the Fairy egg group. It can breed with any male in that group or ditto. All you need to do to get chansey egg moves is breed a chansey/blissey with a male in the fairy egg group that knows one of its egg moves and then the baby chansey/Happiny will know the move.
