Leave it alone. It will be alright.
Humidity How To : When you add water HUMIDITY rises dramatically ! But when water is heated, and becomes a vapour, it rises then saturates the air, then it levels out. Tip ! Tools :

Try and play... See what
Wow!! So very helpful!! Thank you for sending this over! As an update, humidity leveled out after about 30 minutes and is back to where it was. Mallard is resting on the top of the covered water tank in center of bator. Already able to hop up and flop down..lolHi.
Can you do an adjustment of an air vent? Or make one ?
A controlled letting in of air through a vent will bring the humidity down.
[If you open an Incubator... You will get a rush from one extreme to another !]
Humidity is the amount of moisture held within warm air. It rises, circulates cools and condenses.
To be warmed again, rise, roll, fall.
(Think of rain, or a very steamy bathroom.)
Adding water is only part of it.
>> Humidity is enhanced, and increased by surface area <<
AND not water depth !
So...
Use shallow wide dishes, with added sponges. Warm water increases humidity quickly.
External environment effects humidity according to altitude. And if you are in an arid or temperant location.
(Desert is arid, and the Tropics are temperant.)
>> Don't worry if you add water... and it rushes up to 80% or so. After this initial ramp of high moisture, it settles back to a more acceptable % rate.
If your humidity is really high, and your incubator is full of condensation, then yes... you have moisture saturating the air, and it can only turn back into a liquid.
Bring it down by :
1) Having more ventilation, or air circulation.
2) Reducing the area of the water surface. Less bowls, more sponges !
3) Keep the still or circulation of air temperature at a constant level.
Don't open, dump tons of water, close, then open the incubator, and mop excess water up, close, then increase the temperature by a few degrees !
You are on a steep learning curve to failure !
Bring it up by :
1) Adding more 'warm water'.
2) Increase the overall 'surface area'.
3) Add sponges into dishes, or absorbent material into those channels. Doing this means water is covering more surface matter, than the top of the 'water' itself.
4) Know that by knowing your incubator, you could open it up regularly and add 'smaller' amounts of water, to that of dumping lots in one go. (My Janoel 12 instructions says add "100ml" every 2 days ! I get to much condensation (to much humidity.) So... I add more sponges, add less water, but do it more often.
>> If you need it up at Lockdown, but you need to open the incubator, get yourself ready with... a few tools, to
bring the humidity back to the right % quickly, and NOT so it shoots up !
Or you cannot get it up to that higher level of % !!!
Know how humidity works...
Do my suggestions below : WHEN you are not in a PANIC, or affecting your hatch.
To raise humidity :
Add water, sponges, increase water area. NOT it's depth !
Use a warm spray or mister.
Know that if an wet object opens, eg a hatching egg : humidity will rise.
Keep eggs (warm objects) away from cold plastic surfaces, this increase condensation. Raises humidity, but droplets cool things down.
Keep things space evenly from each other. Air circulates, so you don't get hot or cold spots.
To lower humidity :
Add less water. Reduce the surface area. Use a smaller or deeper bowl.
Add a dry material to the floor of the incubator, to absorb that extra moisture. Eg paper towels, have your eggs lying in cardboard egg box trays or lids. Have less shiney surfaces. Water droplets drop down glass and plastic. So make a nest of mopping up material around the edges of your incubator. Try paper towels, dry mini sponges. A dish of Sea Salt crystals, or Baking Soda. (Keep it out of harm's way. Add it to ex eye makeup mini pots, with a ventilation hole here and there. Or try those dinky jam jars you get at breakfast. Even 35mm film canisters... (Showing my age ! )
Anyway hope this debunks things.
And makes HUMIDITY a breeze of good conditions for your hatchers ! And not a fog of despair !
Practice, practice, practice humidity
AND how to deal with it when it goes
splat ....
And becomes your friend and helper.
>> Practice doing humidity control with an empty incubator. <<
Do this over several hours, in different seasons, at day, or night. And learn !!! AND write a note of "what did, or didn't get the effect you wanted."
Hindsight is no use when battling to save those chick or duckies...
happens. Then when its
for real.... You will be ace
at Humidity.
Try : Adding water in channels or bowls only. Do same and add sponges. See what effect it has.
Try : adding faux eggs, eg stone ones.
Or those realistic ceramic types. See what happens if you add a heat sink (an object that absorbs the heat, and gradually gives this back to the atmosphere.) Eg small bottle of water, a water filled glass jar. Pebbles, ceramic tile or dish, a solid metal object. All take the heat 'in' then it releases it back. Think sunshine warming a wall, stone slabs etc.
Heat Sink : Practical use
* Useful to add an item if you think you might have a power cut.
* Really helps tired Hatcher's, snuggle up to a warm object, of body temperature, so they don't have to work hard 'keeping warm,' if they are frail, weak, or so wet, they cannot maintain their body temp circulation !
Hope this helps someone

and tricks.
So eggs hatch to calm owner.
