bad eggs don't hatch, they are just bad and never hatch.

They don't Hatch. All they do is right... EAT your pokemon! I used a gameshark code to have all the berries in pokemon Emerald. A bad Egg appeared i put it in the Pc my pc was full of pokemon when i went to see the next day a ton of bad eggs appeared and my pokemons were missing. I can say this because my boxes were organized by types and evolutions. For example: Grass Box and Bellsprout, Weepinbell and Victreebel. And when you see you may have one of the three eaten up by the Bad Egg. Just a question, you use gameshark in emerald to get mew and you get a bad egg together with mew if you trade that mew to another version will the bad egg go after it?

Bad EGG's don't eat your pokemon. If you think they do you never had a Bad EGG before. Then can appear even if you put the right cheat in. The only time they screw your game up is if they hatch, which they sometimes do, and you go to see their moves.

AAA! I have 2 bad eggs holdin azure flute how the hell!

Bad eggs don't do anything. They DO NOT eat a pokemon. They don't hatch. they can come with status problems or with pokerus. Pokerus is great. Also, if you put your Bad egg into your box, nothing will happen. it will not eat your pokemon. nothing will happen unless he's infected with pokerus. then he will infect everyone

Bad eggs hatch in to a missingo well that's what my friends egg hatched into anyway i don't cheat and i've finished the game so I have nothing to worry about !
