I was lucky to get up to 30%. Most of the time my incunator ran round 25% and all turned out well.I would say that would have to do with the ambient temps you are incubating in. If very high ambient humidity your incubator may run at around 30% without adding water. If incubating in a very low ambient humidity % you will have to add water to get to 30%. Most folks that dry hatch is because they are in areas of very high ambient humidities, and their incubators humidity runs around that 30% without adding water or very little. Also, water surface area in incubator is what determines humidity % not the amount of water added.
I am speaking for my icubator and how it worked with dry vs. wet hatch, which is why I mentioned multiple times the kind of incubator I am using.
Mine ran around 25-30% at 100.5 F.
