How many eggs does it usally take?I have like 20 charmanders now! Is there a way to increase the chance even more?I know its like 2089% or something like that. But i dont want a box full of charmanders.Please help.

The chance is 1 in 2048. With 20 Charmanders you are so far off from a chance of a shiny it's unbelievable.

If you don't know, "1 in 2048" means that if you made 2,048 (two thousand and forty eight) eggs, you would only expect one of those to be shiny.
