Its obvious that my homemade incubator's temps were running a little low at some point.. Today is 22 days with 4 chicks finally out and healthy... all though there's no sign of pips from the other 20 eggs. I've had these in lockdown with 65-75% humidity for almost 4 days now. but since my temps ran a few degrees low should I give these eggs a few more days before chucking them out? -The 1st chick took almost 20 hrs from pip, zip and finally out! 2nd chick was SPEEDY with pip, zip and shell kicked off in less than 30 mins. It was amazing. The other 2 were ready to come on out once they heard the chirping from the 1st one. I've got 3 of the 4 in a brooder now, I left 1 in the incubator for inspiration to the remaining eggs to start pip of their eggs.. Is that non-sense, or is it actually true that if they hear it chirping they'll come out sooner?
