What is the best incubator humidity ??

I've looked all over but can't seem to find a consistent answer. I've hear around 90%, i've heard 100%. What is the best humidity to keep inside the egg bins???? Thanks

Between 90% and 100%

Hope that helps :)

im heard the amb air humidity surrounding the tubs in the bator is fine from 75-80 and 100% inside each tub. of course higher is better without condensation

If you are new at this here's something to remember: Better to be a tad too dry than wet. I don't measure the humidity in my boxes. I've got my system for mixing my substrate and watch the eggs. Any dimpling and you add a little water and see how they react. If you are into watching a gauge that could be inaccurate then the answer is as close to a 100% as possible without soggy substrate.

Which is why i suggest using Hatch Rite with light diffusers so that you can use more water without soaking the eggs.
