Bad Eggs are known to appear when a player uses too many cheat codes on his or her game. Sometimes they appear when trying to cheat for a legendary Pokemon like Jirachi - the Jirachi will not appear, but a Bad Egg will. These Eggs will not hatch by normal means. If another cheat code is used to hatch the Egg, it will usually become a ? or a ??, and the save file can become corrupt. It is rumored that Bad Eggs were put into the game to punish players trying to cheat for rare Pokemon.

Sometimes wild Bad Eggs can appear if a player is using cheat codes unrelated to changing their party Pokemon. These Bad Eggs will usually go away if the cheat device is turned off. It is rumored that storing a normal Egg in the PC indefinitely will turn it into a Bad Egg, but this is unconfirmed.

There are reports that using a Catch Pokemon Easily code on another trainer's Pokemon will turn the "stolen" Pokemon into a Bad Egg. After this, the Day Care can become corrupted - one of the two Pokemon stored will automatically become a Bad Egg permanently. This can also have the odd effect of changing Pokemon's nicknames and causing glitch Pokemon to hatch from the eggs produced by a normal Pokemon and the Bad Egg.

Other players report that a Bad Egg can appear in the PC after certain cheat codes are used. If this Bad Egg is moved to a different spot, it will leave a copy of itself behind in the original spot. There are still more reports of a party Pokemon being replaced by a Bad Egg with Pokerus after cheat codes were used.

Some players have reported that naturally hatching a Bad Egg may produce a blue glitchy block with the moves Hyperbeam, Struggle, ???, and a glitch move. Others report that the game freezes whenever the Bad Egg "hatches".

There do not seem to be any beneficial effects from encountering a Bad Egg. In fact, this seems to be the only dangerous glitch in any of the Advanced Pokemon games. It is not known how a Bad Egg would display inside Pokemon Box. Perhaps this utility would allow the player to permanently remove the Bad Eggs from their PC and party, as Stadium 1 and 2 would allow players to remove 'Ms from a frozen PC.
