I broke the cardinal rule. I opened the incubator during hatch. My first chick fell down through the corner of my incubator where the hardware cloth didn't fit tight and I rescued it. I know, I'll definitely fix that. And NEVER open again during hatch. You live you learn. So, I ended up waiting about 30 hours and some were ALMOST free but I could see 4 of them drying and struggling and stuck! - ended up dampening one, and carefully assisting 3 (tough dry membranes stuck to their heads). They had completely absorbed all veins, definitely ready to come out. Everyone is back in the incubator to dry- humidity never dropped below 55 and now its a little over 70 with all the wet chicks. Here is the question-: The 7 eggs that are still in there have not externally pipped yet. Is there any chance they did NOT shrink wrap because they are still sealed in their shell? or should I wait a bit and go further down the rabbit hole by opening incubator AGAIN, candling to locate a possible internal pip and helping to create an external pip for them? (I'm going to get a wink of sleep finally and hope you have some advice) With assistance this hatch is 53% so far. I have learned my lesson. Thank you in advance!
