Me too, Cyn. I just had a pretty-faced little bantam hatch, as a matter of fact and am waiting on 3 more that have pipped. Hygrometer is reading 66%.
Optimum growth for most species requires a relative humidity of 60 percent until the eggs begin to pip, after which the relative humidity should be raised to 70 percent.

HumidityThe moisture level in the incubator should be about 50 to 55 percent...
I think you may be looking at the wet bulb readings. Relative humidity is usually set at a lower recommendation for days 18-21:
The relative humidity in the incubator for the first 18 days should remain at 58-60 percent or 87o-89oF., wet bulb. Increase the humidity during the last three days...
I agree. It may be a humidity problem.
If it turns out not to be that, another issue could be poor ventilation during hatching. Do you have vent plugs that you can remove during hatch?
