Are they shipped? Humidity isn’t the issue, that is a ‘saddled’ air cell and usually indicates shipping trauma. The whole batch has been through something stressful so even the normal looking ones are more liable to hatching issues/deformity/quitting. The hatching success doesn’t correlate with air cell condition, those wonky eggs can still hatch and your normal ones might die in shell. Be ready for a lousy hatch, 25-50% plus 10% or so mutants (hopefully better but prepare now for the worst!). If they aren’t shipped they’ve still been through the mill! It wasn’t anything you did or didn’t do, and there is nothing to fix or help anything so don’t feel guilty or second guess yourself, but be ready for a sad hatch, sorry!
