Monitoring humidity in egg tub?

[Alicia]

CeeJay, the gauge reading 90% is more likely to be the right one. For most of incubation, as long as the eggs look pretty much as they did the day they were laid, humidity is good.

Would you consider tiny bumps dimples? Maybe I am confused. The eggs are nice and plump. No deflating. Thanks.

Are the bumps raised above the shell, or collapsed in? If the eggs are plump otherwise, keep an eye on it, but I'd be tempted to say it's probably just how they were shelled.
