No fan in incubator?

[AppleCrisp]

Hey. I'm making a home made styrofoam incubator and I'm wondering if its okay not to have a fan in it?
Also am I going to want to poke holes in the side that can be filled to adjust heat?
And lastly can anyone direct me to good instructions to make a simple egg turner?
Thanks,

You don't have to have a fan. A lot of people use them because they circulate the air better. You sound like you have a good plan in place. Sorry, can't help with the turner.

For the turner, if you have a tall - er incubator, then you can craft one out of wire to hold the eggs, then spin it to roll them. Or you could even get a little motor to roll em.
