Think I messed up - low humidity overnight

[ExhaustedBrachiosaurus]

I'm hatching out the 8 mixed eggs that made it to lockdown:
3 Gold Partridge Brahma
1 GPB mix
2 olive Eggers
1 Aracuna
1 Marans

Lockdown on day 18 and the GPB were wriggling, adjusted humidity to 70% and waited. First GPB egg pipped on Day 19 and hatched Day 20 (he's doing fine), second followed later on Day 20 and is hatched. Day 21 and another GPB pipped right before I went to bed. Unsure what happened overnight, but humidity dropped to 43% and the alarm didn't go off. The GPB that had pipped is now shrink wrapped (I'm underway on assisted hatch, have paused due to blood). Is there any concerns for the remaining eggs that haven't yet pipped? It's about halfway through day 21 and no other pipping. Pictures attached of chick and the eggs.

I'm having such bad luck hatching eggs and I'm feeling really low about potentially having ruined this batch. For the record, my first hatch were all early quitters, second batch was 100% roosters.

Any help and advice is greatly appreciated.

Sorry you’re having tough luck. I’ve also hatched all roosters and it’s quite the disappointment. Your babies are cute!

I don’t think the drop in humidity should have an impact on the eggs that haven’t yet externally pipped.

Good luck on the remaining eggs!

You could try listening to the eggs to see if you hear peeping. If you do that means they've piped internally (broke the membrane) but haven't piped the shell yet.

If you're concerned you could candle them and get an idea of where the beak is and create a very small safety hole so they can breathe fresh air.

If they pip externally and seem to be shrink wrapped I chip a small bit of shell on either side of the pip and put a bit of olive oil on the membrane. Then the hard part is waiting at least an hour to see if the chick makes progress on its own. If not chip a bit more and add a bit more olive oil. Once the beak is out you can give the chick a bit of electrolyte water by eyedropper while still in the shell. Go slow and don't rush. Good luck!

Thanks for all the advice. I chipped away some more shell and saw it's beak "chewing" and knew it was still absorbing the yolk. The chick hatched itself out of the shell about 5hrs after I increased the humidity and assisted. 2 other eggs have since pipped

Great news!!

Looks like you are keeping meticulous tabs on your temp and humidity. If these are shipped eggs, even getting to lockdown is so variable in perfect incubation conditions. Kudos and congratulations!
