I scoured a lot of threads and this is what I came up with. I didn't have access to a styrofoam cooler, so I built my own box. So far it is holding a good temp with not much variation, I just have to work on the humidity level. The egg cartons are hot glued to pvc pipe and I can turn them from the outside. They are removable, so during hatch there will be plenty of room for the eggs to lay on the hardware cloth. I have 2 vent holes on each side, empty pill bottles with the bottom cut off and glued to the box. I also have a tube running from the outside for the water pan that I can fill without lifting the top. What do you think? Did I miss anything? If everything holds good I plan on setting eggs tomorrow night. Thanks for looking.
