6 of my 8 quail eggs have hatched 20 hours ago, and there are 2 left. One has a small pip(little crack) in the shell, and the other still nothing. You can hear them both picking( one very soft and the other a little louder) and one of them chirping. It has been 47 hours since they internally pipped, and i am worried they might run of air inside the shell. Should i assist by making a very small hole where they are picking so they don't run out of air, or just wait? I don't wanna put them in danger.
