Earlier in the summer, I was attending an auction with my parents when I spotted something very interesting: an old proofer, probably from a convenience store. I had recently tried and failed to build a cabinet incubator using materials I already had at home, and this proofer looked like a promising alternative to my original plans. Assuming it was in working condition, it was pretty much perfect. It already had a built in heating unit and thermostat, so it wouldn't cook my eggs like my home-made model did. It already had circulated air that would evenly distribute heat throughout the unit... It even had a pan for water with a valve to control how much humidity was produced. The only thing it didn't (and couldn't) have were egg turners, but I already had an idea of how to make that task easier. I plan on eventually building frames that I can push or pull to turn the eggs on the trays, without having to turn each egg individually.

I got the proofer for $40, and my parents and I loaded it up and took it home where it sat in the garage for a few months. Finally, when I had the space, I wheeled it inside and plugged it in to find out if it would even work as an incubator. I was apprehensive--if it couldn't heat up enough or maintain a consistent enough temperature, then there was no point going any further with the project, but after a few days of the temperature holding steadily just under 100º (according to my dinky kitchen thermometer) I decided it was worthwhile to invest in a digital thermometer and hygrometer. As luck would have it, I was able to snag one on clearance for $9, and it even has a remote sensor so that I can monitor the temperature at a glance from my desk where I work.
I gave it another day to make sure I could maintain heat and humidity levels to my satisfaction, and then I gathered together enough eggs to test each shelf of the unit.
To make monitoring the developing eggs easier, I was sure to include at least one white or light-shelled egg on each shelf.
First problem: the eggs like to roll around on the metal trays. I put down cloth to make that less of an issue, but I am going to need to switch to something better soon. I will likely use cheap wash rags as cushions until I've built the egg turning frames I'm imagining.
The eggs are in. Incubation begins!
