Hands on hatching and help

[Mill Chick]

I think my incubator is overly humid (57%) and it is possible my temperatures have been higher than they should be: 100.5 to 101. I had egg movement at Day 15 on two of 7 eggs, and on day 17, all eggs were moving. These are from a jersey giant rooster with a mixed of JG, barred rocks, buff orpingtons and cinnamon girl moms. Day 18 begins in 6 hours. My question is: should I put an emergency air hole in the air space before I upped the humidity for lockdown?

Sorry for the late reply! You know the eggs aren't supposed to hatch till day 21 right? Don't put the humidity so high right now if you had it high earlier. I have never done a safety hole before so I don't have much experience with them so I'm not that much help but I will tag some people for you. @Debbie292d @Eggcessive
