3rd Gen PokeEgg.

[Nexias]

I have a pokemon egg that has this as it's info:

STATE:
It looks like this EGG will take a long time to hatch.

Trainer Memo:
A wondrously peculiar Pokemon Egg obtained at a nice place.

is this a bad egg, or is this a legit egg? I have no idea what it will be.

 

[ErickaVolt]

Just wait until it is hatched.

It's a legit egg. That text appears in eggs got in Pokémon box, if I don't recall wrong.

Walk around with it...Also, carry either a Magby, Magmar, Slugma, or Macargo with you, it halves the amount of steps needed to hatch the egg
