Don't worry about the no peeping, they can't peep unless they have internally pipped.no peeping.
My last run they hatched out 3 days early (reading 99.9 - 100.0) (only 3 out of 13 hatched) so I lowered the temp (99.0) this time around and I put a secondary thermometer in that reads 99.9 - 100.1
I am running it dry and it is staying between 29% - 38% mostly about 30 - 32.
I don't get what I am doing wrong. So confused and disappointed.
