Yes, I don't think she knew what she was talking about.... When you are at the hatching stage how many chambers do you typically flood to get what % of humidity? Any info would be helpful.
I just can't believe 3 of 4 chambers flooded would only give 88% wet bulb reading.
I get a wet bulb of 89 at 99.5 dry bulb which gives me 65% relative humidity with 2 chambers or less.
