Five of nine hatched. Three of the others never pipped but they looked like term chicks. One was breech. Why might term chicks not pip? I did not do a thorough eggtopsy. I should have but I was a little too exhausted. I kept day 1-18 humidity around 20-30%, lockdown humidity starting at 65%.
Day #21, I've had 5/9 eggs pip today, but no zipping or hatching. I kept humidity low on this set of eggs during incubation, trying out dry incubation. Have kept humidity around 20-30% for days 1-19. For lockdown, have kept humidity around 65%. These eggs have been pipped since this morning...
