Urgent help

[BaJa]

Today, I have to display a Science Fair board and my topic is "Does Humidity Affect Hatch Rates." However, I have not come along much info. What I am asking is that if you would please tell me the humidity you used and what the hatch rates or results were. For example: 55% = 87% Hatch Rate.
Thanks a lot for your time, and please be quick, because I have to get the results in before 5 p.m today.

40%-50% humidity for the first 18 days and for lockdown 65%-70% humidity. Hatch rate was 100%

37%=52%, 45% = 75%

The quick answer is that there are too many variables to give you a quick answer.

Yep, this right here. The humidity that everyone needs to use varies a lot by location. So while 30% humidity does it best for me and results in the best hatch rates, for someone else that might kill all their eggs.
