Go to the day care and get a ditto(or a female and a male Pokemon. They haff to be the same Pokemon )then take a Pokemon and putt it in with the ditto.this is called breeding.then, wait for the two to make an egg.(daycare man tells you on pokegear. Pick up the egg and walk with it till it hatches.(do same thing with female and male Pokemon) Hope I helped
Because your Pokemon are still in the daycare. If the two like each other, they will keep making eggs. Take them out of the daycare if you do not want any more eggs. If you do not, they will not stop.
The DayCare is just at the south of Goldenrod City.
give them to daycare. wait.
yes there is an app on the pokewatch
you can leave them in storage or in the daycare
its on the same route as the daycare center
You can find dittos in the grass around the daycare
i am pretty sure the answer is no there is not
They will simply gain Exp. You can't breed legendary pokemon.
You can't breed legendary Pokemon eggs on Pokemon SoulSilver or on any Pokemon game.
One step equals one experience point for the Pokemon that are in the daycare centre
You'll need to breed Pikachu or Raichu with a Ditto or the same Pokemon with the opposite gender at the Daycare.
