personaly,i think that rotten eggs would just decrese on people doing thier hatches and i'm not that fond of the idea,because if you got like, for instance,a leverene egg and it was rotted,it would stink,literally.xPbut relesing unnamed pets is an awesome idea.
geonights idea sounds a bit like a computer game sometimes they hatch sometimes they dont but geonight is right it would be realistic but i dont really like the idea i mean what if you get a rare egg you tried so hard to get without credits and it ends up being a rotten egg. then all that work will go down the drain. but what if there is a limit on how long it can `stay alive and it will stop in trade and restart with a new person?
