Candling is a popular method to determine if a bird egg is fertilized. Hold the egg under a bright light source in a dark room to see inside. Look for veins or a developing embryo, which indicate fertilization. Unfertilized eggs will appear transparent or show just a small dark spot. For best results, candle the eggs between days 7 to 10 of incubation.

  2. When is the best time to candle bird eggs to check fertilization? The optimal time to candle bird eggs for fertilization is between days 7 to 10 of incubation when veins and embryo development are clearly visible.
