You can catch Chansey in Pokemon Crystal on Routes 13, 14, and 15.
You trade it with a girl on route 14 in crystal for a chansey, which can also be found in route 14
You can catch Chansey in the Safari Zone. At the entrance/center there is a 1% chance to encounter it. At the Area 2 there is a 4% chance to encounter it. Throw one rock at it and then throw a safari ball. Keep doing that while rotating on your spot in a patch of grass until you catch it.
Celebi, Dragonite, Togepi/Togetic, and of course, if you raise this Pokémon well, Chansey/Blissey.
Chansey is rarely found on route 14, 15 and 16. Keep on searching that area until you find one. I think it might be available at all times.
