Hi, I was wondering what everyone uses to candle their eggs? I saw actual egg candlers on the internet, but they were a bit expensive (considering they just looked like a flashlight). I know my parents used to use a flashlight with the cardboard that comes out of paper towels. They would sit the egg on top of the cardboard and then shine a flashlight up from the bottom. It seemed to work ok for them, but they wouldn't candle until later in the incubation process. I am getting ready to do my first incubation and would like something that will candle at just a few days so that I will know if the eggs are fertile. Would a flashlight work?
