After you make the hole and keep in mind you may hear him peeping at this time, give them at least 24 hours to make some progress, if nothing then I will take you step by step on how to get his head out ONLY. But I must have pictures at that time so I can tell you if I need you to proceed or STOP... DO NOT TRY TO GET HIS HEAD OUT ALONE.... PLEASE, DO NOT.. If you don't know what you are looking for you will end up killing him...
Now: I need you to BE VERY CAREFUL when making the hole, if you go to deep you will or could hit the chick or a vein and the inside of the shell will fill up with blood, something we do NOT want. Avoid that chick you want to go away from him.. Lets hope that dark spot you see at the lower end is NOT the head, if it is this will be a long, long process because with his head at the lower end, he's considered upside down, his head has to be towards the big end, you see he should be trying to get to the air cell to get more oxygen before he runs out. Right now his limited with being all snuggled in the membrane sack..
But its important that you TAKE YOUR TIME, do NOT rush anything. Do not take all the eggs out and work on one then the next etc. Work on one get him a safe hole put him back in the incubator then get another one. If you take all of them out the other two will cool down, possibly get cold and you've just wasted to lives.
So one at a time and do not rush. You have about 30 minutes for each egg, to make a safe hole, It should NOT take that long the most it should take is about 10 minutes per hole per egg.
IF it starts to bleed, Cover the hole with your finger and try to stop it from bleeding and put it right back into the incubator and work on your next one, once you get the others done in about 2 hours go back to the one that was bleeding and try again, that is if you can still see it moving... If you hit the vein chances of survival are going to be low....
I have confident that you can do this without harming them..
