I've been playing around with the idea of possibly breeding, if I ever decide too I will most likely build my own incubator.

I saw the DIY sticky thread on this subject above. I was wondering what is a good price for coolers similar to the picture below picture below? Working one and not working? How many clutches would this hold?
Can a working be use as an incubator?- Adding the heating elements and not plugging it in?





Thanks for looking
