I need some advice! I'm on day 22 of my incubation with chick eggs. I can see that the chicks have internally pipped but nothing on the outside and I had 1 hatch on the morning of day 21 with no problems but the last 6 are not popping externally.. I candled this morning just to see if there was any movement and there is but not a lot. Should I let them be or should I try to help?? I don't want to lose them as I already lost 1 yesterday. This is only my second batch so I'm so nervous. My temp is at 100° and 65% humidity
