I use an Incuview Incubator. Holds a steady humidity for along time.
I keep my humidity between 35% - 45% for the first 17 days, then increase to 55% to 65% for lockdown.
I use one Hygrometer/Thermometer to monitor the house conditions. I base my temperature, & humidity in my incubator...
It's still early. It's okay. As soon I wake up in the morning I add extra water to boost the humidity back up. You just don't want a long period of low humidity during lockdown, or hatch day.
You can always restore the amount of humidity. But it's no guarantee, if they maybe shrink wrapped, or possibly just sticky.
If necessary, candling to see if they're still alive can give may help judge whether they're going to make it, or not.
