Egg candler is used to scan eggs once or twice during the whole incubation.

 Eggs have to be scanned once or twice in incubation.

Taking chicken as example, the first candling takes place on the seventh or the  eighth day to pick out the unfertilized eggs and dead eggs (this step is not convenient to be used for Tunnel Sytle Incubators); the second candling takes place on the seventeenth day or the eighteenth day when transfering eggs from setter to hatcher to pick out the dead eggs. Our Easy Candlers are portable and easy to use
