FRD-10 Egg Candler
The FRD-10 Egg Candler comes with both small and large focus beams and can be used to test the fertility of most types of eggs including chicken, Japanese quail, duck, turkey, geese, pheasant, and guinea fowl eggs.
The FRD-10 egg candler comes with both a 220-240 volt Australian power plug and portable battery case. The portable battery case allows easy access to candle eggs under a broody hen. The battery case requires three AA batteries (not included).
Instructions for the FRD-10 egg candler, a guide on how to candle fertile eggs written by Poultry Australia and a storage case are also included. Express postage is available upon request at

Candling Fertile Eggs
The best time to candle eggs is at 14 days into the incubation process. Trying to candle eggs without a proper egg candler is inaccurate and will not show the development of the embryo.
For the most accurate results, eggs should be candled in a dark environment. Candling can be used to check the fertility of eggs set under a hen or in an incubator. Try to limit the time that the eggs spend unincubated to under five minutes. Never candle eggs after the 17th day into the incubation process.
an egg, hold it up against the egg candler with the round side of the egg facing the light beam (pointy side upwards) produced by the candler. It is a good idea to first candle an egg that has not been incubated to see how light travels straight through. When candling a fertile egg the light will be blocked by the developing embryo inside. The development of membranes within the egg should also be clear.To candle
It is often possible to see movement within the egg at 14 days.
