6 eggs have little tiny holes in the shells. Maybe more I can't see some of them properly. Lots of little chirps in there
Questions on terminology: What's the difference in pipping, zipping, etc?
The two circled in gray...they are pips. The one on the left is a fresh pip. Chick is just pushing through the shell. The pip on the right is a farther along pip where the chick has broken out a couple good size pieces of the shell. On the bottom circled in red is a zip. The chick is actually working it's way around the egg in preperation of pushing out and hatching.
