Chancy is a swarm pokemon, that is; it appears at places around the region according to the radio program. However it is only found in soul silver, heart gold has a different variety of "swarm pokemon" available to silver.---------------'NOTHER ANSWER: u can trade from diamond, and many pearl and, the other one. When u battle a pokemon trainer with a chancy, it will let u know where to find one, forgot where, and u can get an egg that hatches to a happiny, train it good and have it become a really good friend, it will evolve, and...VOILA! u got your self a chancy.
Happiny evolves into chancy evolves into blissy.
I would say go for a chancy or blissy the have a very very high maximum HP I have seen some with over 600 Hp at level 100.

go to the safari zone
You can't, sorry.
Its happiness must be high.
you cant evolve Chancy by training it. you have to make it happy by walking around with it in your Pokemon party.240 steps = 1 happy level. hope that helps.
