Also, this being Week 2, I'm finding the humidity dropping rapidly, as in not staying very stable within the given range. Twice, I have found it at around 20%. Are the eggs sucking in moisture?
Mind you, I was out last night and could not check it 4-5 times, as usual. And this morning it was that low, again.

As the embryos grow they produce heat and that affects the temperature and humidity. I found I had to check less to avoid insanity!

We first timers get a bit anxious, I guess! And that brings to mind, there must be some growth in those eggs! This is good!
And... with the more questions I ask, and info I look up, eventually I find what works for me.

The eggs need to lose moisture as they incubate so should not be sucking in moisture if humidity is too high moisture will move into the egg if humidity too low than too much moisture will lost from the eggs.

So, Killerbunny is correct in saying that it is most likely the eggs giving off heat the reason for loss in humidity?

Yes, @Killerbunny knows about these things. :-)

Yes developing chicks giving off heat can change your humidity reading because you are measuring relative humidity not the actual amount of water in the air. And warm air holds more moisture than cooler air.

I realize this is changing things midstream, but while turning the eggs this morning, I took out the pieces of paper towels. This will, hopefully, ease any addition of needed humidity during lockdown.
Now the eggs are on the metal screen.

My sponges stick out of my water container so as water evaporates it wicks more moisture up the sponge, the water container has no lid.

Why do you have paper towels under your eggs? I would worry that when chicks are hatching and wet the paper towel might stick to them.

Some times on top of the wire in my styrofoam incubator I have used cheap rubber shelf liner that was kind of honeycomb like.... decreased rolling and cushioned eggs but did not absorb water or stick to chicks and air flowed through it.
I could cut this to size and put it under the eggs tonight while candling. It is really for a floor rug to make it non-slip. It would definitely help stop the eggs from rolling along the semi-wavy metal screen. It would also allow for air circulation and addition of water for humidity adjustments.
Is this what you mean by a rubber shelf liner?

I use J-Cloth, easy to cut to size and clip to the the wire and makes clean up much easies
