I have had the eggs in the incubator since last friday, just want to make sure all is right.
According to the digi thermometer the temps fluxuate between 87.9f and 90.1 f. I am usinng an on off thermostat. This is the temps in the bator, no9t the egg box. I am going to reset thr min max on the thermometer and take the temp inside the egg box for a while.
Will this fluxuation be harmfull to the eggs?

also the eggs have a couple of dents in them, is this a worry? The humidity in the egg box is 99% according to the digi hygrometer., there is no condensation on the eggs or walls of the egg box.
If I need to boost humidity any will a spritz from a sprayer be ok, or is that too much humidity.
I candled agian and the veins are thicker so that should be a good sign.
how often should you open the egg box to allow for fresh air?
I was thinking 1 time a week.
