Humidity in egg tubs: how much is okay?

[ChuckSM]

When my female laid 9 eggs, she kicked one out as well but it looked just as healthy as the rest. It candled fine and the baby is just as the others. I can only think that maybe she thought this would be a problem child and she was picking favorites

well i had to buy chilled water bottles, as that's all they had. so they're in the sink with warm water right now to heat them up to room temp.

a question i thought of earlier:

when i found that the female had laid her eggs, she was only curled around 4 of them. one was outside of her little "nest." they all candled okay, but does this mean she knows it's going to go bad? unfortunately i didn't think to mark the one that rolled out.

obviously i am incubating all of them regardless, but i'm just curious if anybody has ever noticed that roll-outs go bad.
