Cracks indicate that the egg will be the first to hatch, or will hatch soon. They're only up for today so if no one wants them they'll just go to waste. Be careful which one you pick one of them is supposed to be a joke. I'm only letting 3 people choose the same egg they want, I'll enter their names in a spinner and whoever it lands on will get the egg. They all hatch in like idk when but not to far from now.
