Only chip around the Aircell, the duckling may still be absorbing yolk. If he's is yawing that's a good indicator he is still absorbing. The ducklings should be fine, just let them dry up and pop them in their brooder
If its been 24 hours without any progress, I would slowly start chipping away where you started the safety hole, If you see any blood or red veins stop immediately and put back in the incubator, If the eggs seem dry or sticky you may need to help the duckling. You can apply coconut oil around...

How long since the baby internally pipped, Do you hear any chirping or movement? When did you make the safety hole? Is this the one with the yellow membrane?
White membrane is a good sign, a yellow membrane may indicate a sudden drop in humidity levels. I would pay close attention to the one with the yellow membrane, Only open the incubator when necessary and make sure to keep the humidity high, avoid moving other egg’s around this time too, they can...
Try to open the incubator as little as possible, you will want to keep the humidity high during the last few days to prevent shrink wrapping. Opening it once more tonight should be fine just make sure to keep the humidity high.
Looks good to me, If you have to do the other egg's do it on the top of the Aircell to prevent them from turning and blocking the safety hole, I wouldn't worry about this egg though.

Do you have a picture? Really as long just the tip of the screw went in you will be fine, It's definitely not a life or death procedure. I always put safety holes on my call eggs, most of mine are higher quality so their bills are short and quite often get stuck. Let us know if any of them make...
