we have a brinsea 380ex in the book it says to turn it up to 60% humidity 24-48 hours be for they hatch but we have 2 other trays that went in after the first one so if we turn it up 24 hours before would it harm the other eggs???
I have done a staggered hatch in the past and they turned out fine. I went from 35% humidity to 50% humidity for the hatch. Then when they began hatching it jumped up to 80% for a while. but majority of the eggs hatched. I sort of like the staggered hatch because then you have a couple of days of hatching.
