Another Test

I then thought perhaps it was due to the hygrometer standing straight on top of the wire which the eggs aren't (they are still on takeaway lids), so I placed the hygrometer on top of one of the lids along with the eggs where the measurement should be taken, and humidity seems to have dropped considerably, but since I had the lid opened I'll have to wait a while till I take a proper reading.

Update: 2:46AM- Temp, Humidity both perfect at 37.5 degrees C and 70% RH. :D I noticed one egg which seems to have pipped (??? hopefully...) or accidentally cracked somehow.
