Humidity and eggs and VPD

[Artistickatt]

I have several Peafowl eggs going into lockdown this week and I am getting so final weights. My thermometer actually tracks vapor pressure deficiency VPD. We use it in gardening a lot indoors and I track it for my indoor plants. It seems to be useful when dealing with incubator eggs, because it specifically measures transpiration rates. Usually we are roughing that by the calculated weight loss.

Has anyone else looked at this?
