I have been maintaining my humidity at 70% since day 18. I think at least two eggs don’t have chickens that are alive but i never take out eggs this late. No peeping or movement. With most of my hatched i don’t get pips until late day 21 or day 22 but to my unlucky all of those hatches had the power go out during incubation but i haven’t had the power go out this hatch. I started off with normal humidity then i did a dry incubation. So, why no pips?
