Fan kit giving false hygrometer reading?

[juliasflock]

I have a Hovabator 1602n with a fan kit and auto turner. I use a reptile hygrometer that I calibrated. The relative humidity in the house is 44% but inside the incubator the hygrometer is only reading 15%
I would think the inside incubator air should be the same relative humidity as the room

I had a couple of sticky chicks last hatch, even though I only added a couple tablespoons of water day 1-18, but really had to add a lot of water on lockdown to get up to 65%
and struggled to keep the humidity up, I was adding water every 6 hours and used sponges.

Wondering if the fan kit is causing an inaccurate read on the hygrometer. I am not going to add any water this time 1-18, and only add what I think for lockdown, and see if it makes a difference.

Because the inside of the incubator is much hotter than your room temperature is, it is impossible for the humidity to be the same in the incubator as it is in the room.

If the ambient humidity of a room is 60% at 70°F, an incubator in that room that is running at 100°F without any added water should have a humidity in the low 30% range.

Since your ambient humidity is 44%, a humidity of 15% inside the running incubator is to be expected.
