How much fresh air?

I am almost done with my incubator, if my thermometer/hygrometer is right, it holds its temp and humidity best when the vents are closed, but it starts to drop when the vents are opened. How much fresh air does the incubator need in order for the eggs to survive?
 
I THINK a "Good Supply" is necessary for infusion of Oxygen.

How MUCH? ....Now, THAT would be difficult for a "Backyard" researcher to measure or answer.

Shall we just say: a steady, regular, exchange of air...??????????

What I should have said is how long. Do the vents always need to be open? Can I open them for a little bit each day, etc...
 
It depends on if your incubator has a fan or not. If there is a fan installed, it does its own exchange of air and the vents do not need to be opened (unless humidity gets too high). If there is no fan installed, vents should be opened as you go through incubation to allow for additional oxygen for the growing embryos.
 
bit horrible to have bator without vent opened, imagine you're inside that bator and with so little amount of oxygen and the CO2 keep growing as you're breathing, soon the oxygen will be changed with CO2 and soon you'll feel lost of power and unconscious and in few hours..... all is lost.

that's why you must have at least one or two vents opened to make sure the bator have good air exchange, fan only *rotating* the air inside bator to make sure there's no hot/cold spot inside bator, fan can't produce oxygen.

i guess the vent is located at the side of bator, that will be good to have vents located at side of bator, not the top since it will make sure the temp/humid not fluctuate too much, if the vents located at top, it will be hard to keep the temp/humid stable since the law is hot air rise.
 
As far as how many vents? If I had to give a number I would say one pencil sized hole in the top an bottom for every dozen eggs. That would be a minimum for the eggs to not suffocate. To get the right evaporation/moisture loss from the eggs you would need more. How much more would be hard to say. Here's something on Humidity an Ventilation .

I really think you are better off having to much ventilation an making up for it with more humidity. You only really have to much ventilation if you can not get the humidity up to where you need it for hatch no matter how much water surface you have.
 
I have two pill bottles on either side and on opposite ends for ventilation. So I can close them easily if I have to.
