I have about 6 eggs in my pc but not one of them has hatched and I have had them for about 1 month now. They don't do anything so I just leave them in my pc.
I have never had them in my party because they are kinda useless since they are just eggs. So how do I make them hatch in pokemon pearl?
Pokemon eggs stored in the PC will never hatch.
Best way is having Pokémon with Flame Body or Magma Armor in front of party and ride bike for about 2,000-10,000 steps (each Pokémon has different amout of steps to hatch needed).
What you have to do is keep on riding up and down Solaceon Town and once in a while you should check the summary of your eggs (optional).
Keep on riding up and down untill a speech bubble with the word "Oh?" on pops up. Then.........wa la! The egg has hatched!
oh kay best way is to get a pokemon with the ability "flame body" and but him first so that he is walking behind you (in you have heartgold and soulsilver) and have all the egg behind him. then walk or ride up and down "where ever you want " and it will cut the hatching in half....
