There is no need to make a safety hole is it hasn’t internally pipped first. The point of a safety hole is to give more time AFTER internal pip if one is taking longer than expected, and we get afraid that it may run out of air in the air cell. If it doesn’t internally pip on its own, it’s not getting air anyway, so a safety hole is unnecessary.
Maybe your incubator is running a little cooler than expected? They can take an extra day or more if the temps were a little low. If they are still moving, be patient.
