Could not use the auto turner for turkey or duck eggs because the tops of the eggs would hit the heating element. So, I made an extention ring out of styrofoam to make the top of the incubator (which the heating element is attached to) sit 3 inches higher. So far it is holding a steady heat at 99 degrees, which is the temp recomended for turkey eggs. I guess I will find out if my little extention ring invention was a good idea in 28 days. Has anyone else on here ever thought about doing this?
