Next time just leave the baby alone :) Deb is right, it will make it or it won’t. Messing with it in the egg only lessens it’s chances. If it had died, you would know it eventually by the smell and cloudiness. Curiosity led you to “check” and made zero positive difference. Sorry but true. Any time I cut it was many days after first pip and a slit the width of the average size head. Never even peaked inside. Just in and out fast as possible. The surprise is most of the fun in this ya know.
