ventilation?

[harris farm]

is ventilation all that important? I have a home made bator that has 3 hole already in the back. I closed 2 last night and the temp and humidity shot up a lot. I understand that part but i read some about vents on here and not sure why its so important. Please explain

It is very important - but you don't need very much!

As the eggs incubate they let off CO2 just like you and I breathing. So you need that to get out & fresh oxy to get in.

My home made sounds like yours - I had four 1 inch holes & found I need to cover 3 of them during lock down in order to get the humidity right. Plus I cover two off & on during incubation just to control things.

I was surprised at how little fresh air needs to get in there - but you do need some.

Here's my page on ventilation. http://cmfarm.us/ventilation.html

One hole high an one hole low is best. For my sportsman clone that has 12 dozen eggs those wholes are each the size of a quarter. If your incubator is half that then the vents can be too. My first incubator was the size of a cowboy hat box an only had a leaky door an no real vents.
