still air bator for hatching?

[klf73]

I have a homemade bator, with a fan. I wanted to make a still air bator for hatching so not to ruin my other eggs since they are 5 days behind the first. Is this ok? Is there any reason to not have a still air for hatching? downside?
Thanks

To be honest, a still air is the way to go to actually hatch the eggs. The forced air is best to incubate, but it dries out the eggs easier than a still air does for the actual hatch.
