Walk around. That's how it is in every Pokemon game. How could you not know that?
Breed eltabuzzs and hatch the egg
there are none
A faster way to get an egg to hatch is to ride your bike.
run around til it hatches with it in your party
a minimun of 5355 steps.
Since you can't catch houndour your going to have to trade the Pokemon colosseum houndoom to firered breed it then hatch the egg to get houndour or you can get one from emerald's safari zone.
keep it in your Pokemon party and walk around heaps. eggs hatch after you've done a certain amount of steps. it's a togepi!
you need to have access to go to fourth island have a ditto and put it on it and have another Pokemon and the egg will hatch and the Pokemon will be holding the nugget
Any Egg requires a certain amount of steps to be walked, ran, or biked in order for it to hatch and depending on the pokemon inside it may take longer to hatch. Also having a pokemon with Flame Body in the party assists in lowering the amount of steps that are necessary.
i think it is around 1,956
No.
In Pokemon firered you can't, but in Pokemon leafgreen you can get it then trade it to Pokemon firered.
