I am a first-time egg incubator and am anticipating candling my eggs for the first time in about a week. I do not own a dedicated candler or flashlight, and am looking for recommendations for a setup that will be effective in evaluating light brown eggs. I am open to making a DIY candler, but am not sure what amount of light output I would need in a flashlight. A commercial candler would also be an option, especially if it's not much more expensive than a functional flashlight. Many thanks!
