Question about incubator fan

[willow]

Hi All!

I have a question about my incubator. I have a standard styrofoam one and I just put a fan in. Now, is the fan supposed to vent in or out?

I'm gonna have goose eggs in it.
I know it's a gimme answer but I still want to be sure.
Thanks!!

The fan is suppose to be inside circulating the air.Thats about all I know.If you look here https://www.backyardchickens.com/chicken-coop-incubator.html you will see how the fans are all inside.

the fan should blow upward at the roof of the bator
