It Takes 5100 Steps to Hatch Staryu EGG
Yes. Apparently it is easier to hatch shiny Pokemon from an egg in Platinum if it's parents are from another country.
There is absolutely no way to hatch it.
Don't hatch it unless you want your game deleted.
In PokeMon Platinum The Answer is 5301
Well it really depends on what Pokemon the egg came from like my personal favorite Riolus take about .... 3000 steps as for Torchic .... somewhere in between 3000-4000 steps. (my personal favorite Pokemon is a Lucario so i breed a whole bunch of Riolu eggs)_____/ |_ \| __| | ||__ || | < __________\____/ |Thats not very good..........|
If you are talking about the bad egg, it does not. That's why it is called a bad egg.
