Egg Tub Question

My egg tub is set at between 88F-90F and the humidity is at 99%.

Is that were it should be set at?

Thank you.

Try to keep the temp a little more stable. You want the least amount of variation as possible. I keep my thermostat set to 88.5º but it sometimes dips down to 87º

Im not to worried about the temp as I am with the humidity. I heard that the humidity is supposed to be kept at 100%

That is correct. Your eggs will tell you if the humidity is too low. They should be plump, not wrinkly. A week or two before they hatch, they will start to look deflated and wrinkly, that is completely normal.

You don't want more than a few 10ths of a degree temp fluctuation for the most part. I keep my thermostat right around 89 degrees and usually have a slight fluctuation between 88.7 and 89.2. I see the fluctuation mainly after opening the inc to check the eggs and wipe off any excess condensation once per week. Your humidity is fine.
