This is my first time hatching calls. 25 completed days at 1 pm today. I noticed shadows in the eggs at day 23, two days ago. I made a safety hole in two of the eggs as I had read to do with calls. However, I am not sure they are actually internally pipping. It looks like the membrane is just pulling away from the shell and going up into the air sac with the ducklings. My incubator is set up in a way that I can stick my hand through an access hole with a small flashlight to take a peek without sacrificing the humidity, which is running at 70-75% for lockdown. Do I just need to wait longer or
