Then they should be hatching within hours. Watch the zipping for steady progress. Check your humidity. If that is 60-65% you should be OK.

You want to keep the humidity up. If it's been externally pipped for that amount of time with no progress, I would intervene. I don't let mine go over 24 hours w/o at least starting an assist so that I can assess the position of the chick and make sure that it can progress.I added some more water this morning to raise the humidity. It's was around 45 this morning. I'm getting disappointed
When I assist I get some q-tips water and tweezers. I wet the q tip and moisten the membranes then I proceed by chipping just the shell away and moistening the membrane. If the membrane is free of prominent veining I will pull that aside as well. I will make a zip around the egg, continuing to moisten the membrane and pulling it back as long as there is no veining. At the first sight of veining or blood, I moisten the spot and return them to the bator and give them time to progress on it's own. Many times they can progress on their own after the initial help. Sometimes a complete assist is needed. 3 days after an external pip I would not expect to see veining.So do I help by gently cracking the shell??
