I don't know If there's already a post on this, I did a quick glance but not much of a search, but I recently found out that there has been dangerous Mystery Eggs and Corrupt Pokemon floating around on Wonder Trade and another person got a corrupt Mystery egg randomly from his game and It can corrupt your pokemon!
Since I can't post links, I can't show you where I got this information but there is a video on youtube about it.
They say
-Make no attempt to hatch, touch, move the egg
-Get all of your pokemon out of the box it appeared in
-you cannot release or delete it so don't try
I don't know if its totally true but better safe than sorry.
Just to pass along a warning to those who wonder trade. Due to people trying to wonder trade off hacked pokemon, they will appear as "Bad Eggs". They cannot be traded or released, and they will multiply until it fills all of your boxes. This will also delete any of your pokemon that are stored in your boxes as it will replace them with bad eggs. Trade at your own risk!
Okay, just to follow up on our previous post about the "Mystery Egg" issue, here's what we know at this point.
The earliest report we have of the Mystery Egg glitch is from a player who posted a video to Youtube shortly after the games were released. This video can be found at

At this point in time, it is not clear exactly how these eggs appear in your game. While there have been some people recently warning people about the potential of receiving these eggs via Trading and Wonder Trade (most notably, suggesting that hacked Pok?mon traded via Wonder Trade may appear as these eggs on the receiving end), we cannot at this stage actually confirm that this has occured. It may be that this is simply an unfortunate glitch like the Lumiose City save glitch. If so, we hope that Nintendo and Game Freak will issue a patch to rectify this issue now that more people are becoming aware of it.
