If you hear chirping from the eggs that means they have successfully pipped into the air cell. This is when you want to make the safety hole. If the chick has not internally pipped into the air cell the safety hole will be of no use.Thank you! How would I know it’s time for a safty hole? I currently have them sitting upright, air cell up.
When I make a safety hole I use a screw and carefully score the shell until it makes a pin-sized hole.
