Hey! Thanks for the reply!
Yes it's the tray that comes with. So i started off with one well the 2 then 3 them all 4 and it all reads the same on both monitors. It's so frustrating!
We have a hova bator we got from a friend which no matter how much water I put in there humidity stays at 35% and I have 2 different thermometers in there. That are a few % between both readings.
Any ideas anyone?
