Humidity in egg tub?

Hi guys, what humidity should it be inside the egg tub? How do you make the humidity higher or lower inside the egg tub? Please share knowledge! TIA!:)

Humidity should basically be as close as possible to 100%. Setting up an egg tub using either using substrate or using the substateless + diffuser will generally get you the correct humidty. Use press n seal or similar between the tub and lid until the eggs start to dimple at around day 45.

Mine are at ~98%, using vermiculite mixed with water under a light diffuser panel and Press N' Seal.

How would it be close to 100%? What should be done in order to make the humidity 100%? I have an egg tub with temp 86-88F but the humidity is only 66%, what should I do to increase the humidity? Help please! its the first time I have eggs! This is my first clutch! TIA:)

I use 1 16qt Sterilite with vermiculite as my substrate and I do also use press n seal before I close the lid of my egg tub. :)

Like a few others mentioned, I also use Press N' Seal or cling wrap on top on the egg box, under the lid. I'm using two different materials as an experiment on which I prefer. So far, I think I like PNS more because it doesn't seem to collect condensation as much as cling wrap.

I don't use anything but a 7qt locking lid tub and I even add holes to lower the humidity a touch to prevent mold.
You do not need 100% humidity to hatch eggs, I've had eggs hatching perfect with 85 to 90 percent humidity.

There's a lot of ways to set egg tubs up, you kind of have to play with it well in advance of having eggs in it so you can get your humidity and temps where you want them.

Thanks for the information. So it's alright at 66% Humidity? But how can you make the humidity higher? Add water in the substrate? I am using Vermiculite directly on the eggs, not substrate less method. I am so excited to hatch my eggs! Good luck in you eggs guys! Hope we all hatch and have a happy season!:taz::banana:

I'm going to say 66% is too low but I cannot say for sure. If the eggs are in the vermiculite and it is properly hydrated, you should have no humidity issues. If it is too dry, you will see the eggs start to cave in/dimple prematurely as a sign of lack of hydration.

Yeah I know 66% is too low, how can I make the humidity higher? Any advice that you guys can share?:) So far, the vermiculite is properly hydrated. The eggs are not caving in, but I am a little worried because it might get into that stage, any advice?:tears:
