Is my humidity too low?

    Hello I am in a locked down incubator just locked it down yesterday and my humidity is 59%, but there is condensation on the windows and I am worried that the humidity is higher than what is told. I have a Little Giant still air incubator and my temp is at 101.6 I do not know what to say and my chicks are suppose to start hatching Monday. It is my first time having chicks and I have a mix of eggs so I do not know what is what.

    Condensation on plexi window is sure sign of more than enough humidity. When this hatch is over do a salt test on your hygrometer. If it's an incubator with integrated hygrometer then you'd need another small hygrometer to salt test then compare the two to calibrate. So in a nutshell nothing is good or trusted unless calibrated first. That means all those units with built in hygrometers are useless as you must purchase one to calibrate anyway....

    Plenty of links to salt tests but I'll put down what I do:

    Fill milk jug cap or any cap with salt then add drops of water until saturated. I pour off any resulting standing water or add bit more salt.

    Put salt cap and hygrometer into a sealed container and wait minimum of 4 hours. I use a zip seal quart bag and allow it to pillow with air before sealing.

    A salt environment is 75% RH nearly exactly for all normal room temp ranges. Take your hygrometer reading and subtract from 75 for your calibration. Ex. your reading is 84 then 75-84= -9 you'd always subtract 9 from your reading for true RH.

    Write the calibration on masking tape and affix to incubator as reminder. Low charge battery and so on can cause reading to change. I do a salt test each spring before hatching and after any battery change.
