It is day 19 in my incubator, and I noticed that an egg is cracked about an inch across but not from pipping. I ignored the rule and quickly grabbed it from the bator and re-sealed it at once to check this out...If I put pressure on the egg, you can see the crack widen a little. No smell from the egg. The egg is a dark brown so I can't tell from candling if there is definite movement but the embryo seems to be the correct size for the date...no peeping. What would you do? I'm afraid to leave it in bator because I don't want an exploded rotten mess, but I don't want to remove it for fear it is really alive...what to do???
