My toddler snuck in to the closet where I am incubating and tried to help me "turn" the eggs. He then put it back, closed it up and I just noticed when candling that it is cracked. It is a small crack with a definite center point, but it is not so cracked that it seems to be extra fragile or leaking. I am still assuming this one is done for, correct? Or is there any possibility that it might survive with the cracked shell?
