These are just larger versions of what I built last year for my corn eggs. They are still shipping styros for fish, just a bit bigger then normal. By being larger I can incubate more than one clutch at a time in them.
The egg boxes are filled with vermiculite and perilite.
I'm using the plastic grate method I see a lot of people doing now. It certainly seems like a good idea to me.
The one on the left is slightly larger then the one on the right so for that one I use a 150w tronic heater. The one on the right I use a 100w tronic heater.
Thanks for looking,
Trevor
