I have 46 eggs in the bator, 1/2 from a seller and 1/2 from a very generous friend. One sent from Idaho, one from Tennesse. Both sets of eggs seem to have very big air cells at day 10. I was going to dry hatch, but with the air cells seeming so large even in the beginning, I kept humidity at 30-35 with a calibrated hygrometer. The air cells haven't gotten smaller or bigger, but they appear to be the size of the air cells in the diagrams you see from day 1. Is it normal? Should I add more humidity or just leave it as its supposed to be. BTW, I saw an embryo move for the first time while I was candling! Very very cool, and it makes me insanley anxious for hatching day.
