I have 3 eggs that have externally pipped the wrong end of the shell. One I can see its beak and the other two just pipped in the last hour. I've read about assisted hatching and I've helped chicks before with success. I'm worried about opening the bator when I have some many pips, humidity is between 67-74% the eggs membrane looks dry where I can see its beak. That egg pipped about 4pm today. Do I wait until tomorrow morning to help? There are two chicks hatched and drying right now. Also it's only day 20. Should I make sure the other pipped eggs on the wrong end can breathe?
