still air incubator questions

[apc]

Ive never used a still air incubator and now have a hovabator one. any tips for using one would be great. How do they differ from others?

keep your temp at 101.5 on top of the eggs. i added a fan to mine from incubator wharehouse. temp stays very stable now. i think it was 30.00 shipped. with a fan the thermomter can be anywhere inside. still air it needs to be on top of the eggs. my hatch rate has improved with the fan. with a fan the temp need to be 99.5
