Q: I’m following your website instructions for building a styrofoam egg incubator. But I am having trouble finding a 110 volt type thermostat. I know a furnace thermostat won’t work.

A: I love the process of incubating eggs! I love it so much that I wrote several handbooks on how to do it in a classroom setting. You can buy an appropriate thermostat from a number of online vendors. I found mine at www.mcmurrayhatchery.com among the replacement parts for their picture window incubator.
