no you can get as many as you want
Chansey is found in the safari zone only.
the only way i know of is to trade it from firered
Yes, but only after you get the national pokedex.
Since you can't catch chansey you need to trade one from firered, leafgreen or Pokemon xd gale of darkness.
I leveled up chansey to level 37 and forgot to give it a carbos one level before and it did not evolve.
blisey
you cant get happnie in Pokemon fire red only in the newer games
You can find Chansey in the Safari Zone in Fuchsia City. Though, it is incredibly hard to find. It is a about a one percent chance to find it.
you can't unless you trade it from another game.
The only way you can get a Lucky Egg in Pokemon FireRed or LeafGreen is to go to the Safari Zone and catch a Chansey. It's very rare to get one because it's only a 5% chance a Chansey will be holding one. Chanseys are very hard to find, catch, and they always run away. Also if you have Pokemon XD you can get a Lucky Egg by doing a quest and then trading it to Pokemon Ruby, Sapphire, Emerald, FireRed, and LeafGreen versions.
Chansey can only be found in the safari zone, but it is very rare, and even when you find it, hard to catch. I do honestly wish you good luck, because you are really gonna need it.
Wild Chansey can sometimes hold that item to find Chansey go to the safari zone.
