Well, dh made me a homemade bator last year that holds 7 dozen eggs. I figure with all my projects I will be hatching a lot this year. The problem was the constant temp flux, which is why I didn't use it very often(I used my other 2 styrobators). I bit the bullet and ordered a Ranco digital thermostat, it was recommended by someone (sorry can't remember who) and dh said I spent so much time stressing over keeping the temp right that I needed to get it. He is such an enabler Now I just have to figure out how to install it next will be a different heating element, any suggestions?
