New Brinsea Oct 20 Advanced incubator arrived today. It's fired up and running. No eggs yet. This version has a digital temp and digital humidity read out supposed to be factory calibrated. Temp is dead on at 99.8F and holding with .1 degrees at all times, making it pretty believable. I put water in the wells and I put the walmart digital temp/humidity gage in the incubator. I had put this walmart version in the plastic bag last week with the 1/2c salt and 1/4c water combo to test it. It was dead on at 75% humidity. I have a second gage (bemis) that is 1% higher than the walmart one. So walmart one is inside the incubator and reads 99 degrees and 38% humidity The Brinsea digital read out is 99.8F degrees and 45% humidity 7% seems like a lot and I'm not sure which to believe After reading all the humidity threads and on the advice of the woman selling me the eggs, I was thinking of running 35-40% humidity for 18 days, then up to 50-60% for hatching. (closer to dry method). Advice? I'd love advice from anyone who has experience with this kind of incubator and the outside humidity vs inside incubator humidity......... does this matter? I'm starting eggs this week and VERY anxious to not kill them!
