What Is Egg Candling and Why Is It Essential for Fertility Checking?
Egg candling lets you peer inside developing eggs using bright light to reveal what’s happening during those crucial first days of incubation. This time-tested technique separates successful hobby farmers from those who waste weeks on dead eggs.
Understanding the Candling Process
Candling works by shining a focused light source through the eggshell to illuminate internal contents. You’ll hold the egg against the light beam in a darkened room, creating a glowing window into development.
The process takes just seconds per egg once you develop the technique. Modern LED candlers make this easier than the old candle flame method our grandparents used.
Benefits of Checking Egg Fertility Early
Early fertility checking saves you time, electricity, and incubator space by removing duds within the first week. Dead eggs can explode during incubation, contaminating viable eggs and ruining entire hatches.
You’ll also improve your breeding program by identifying which roosters and hens produce the most fertile eggs. This knowledge helps you make better pairing decisions for future seasons.
Signs of Fertile vs. Infertile Eggs
Fertile eggs show spider-web blood vessels and a dark spot (the developing embryo) by day 3-4 of incubation. The blood vessels branch outward from the embryo like tiny red highways feeding the growing chick.
Infertile eggs remain clear with just the yolk visible, or show a blood ring indicating early embryo death. Clear eggs with no development should be removed immediately to prevent bacterial growth.

The narrow beam means positioning becomes critical â slight movements can obscure developing embryos. It’s perfect for occasional use but becomes tedious when candling large batches. Consider this your entry point, not your permanent solution.
Factors to Consider When Choosing an Egg Candler
You’ll find success with fertility checking depends heavily on matching your candler’s capabilities to your specific needs. After researching dozens of models across various flock sizes and egg types, these four factors determine whether you’ll get reliable results or frustrating guesswork.
Light Intensity Requirements
High-intensity lighting makes the difference between seeing clearly and squinting hopelessly at dark-shelled eggs like Marans or Barnevelders. You need at least 100 lumens for white eggs and 300+ lumens for thick brown shells.
I’ve watched beginners struggle with weak flashlights for weeks before upgrading to proper candlers. If you’re working with heritage breeds or mixed flocks, invest in adjustable brightness from day one.
Egg Size Compatibility
Your candler’s opening size determines which eggs you can actually check effectively. Standard chicken egg candlers work perfectly for bantam through large eggs, but struggle with jumbo varieties or waterfowl eggs.
Duck and goose eggs require wider apertures for proper light distribution. I learned this lesson the hard way when my first candler couldn’t accommodate my Buff Orpington’s oversized eggs, forcing awkward angles that missed developing embryos.
Battery Life and Power Options
Battery-powered models offer flexibility but die at the worst possible moments – usually halfway through checking your largest batch. Rechargeable units with 50+ hour runtime prevent midnight charging sessions during critical candling windows.
Plug-in models eliminate battery anxiety entirely but tether you near outlets. Consider your typical candling location and session length when choosing between convenience and reliability.
Price Range and Budget Considerations
Budget candlers under $30 handle basic fertility checking for small flocks perfectly well. You’ll sacrifice adjustable brightness and premium construction, but core functionality remains solid for hobby-scale operations.
Premium models exceeding $100 justify their cost through durability and advanced features only if you’re managing multiple incubators or commercial operations. Most backyard breeders find the sweet spot between $40-70 for reliable performance without unnecessary extras.
How to Properly Use an Egg Candler for Fertility Testing
Using your egg candler effectively requires proper technique and timing. The key to successful fertility testing lies in creating the right conditions and knowing exactly what you’re looking for.
Step-by-Step Candling Process
Turn off all room lights and find the darkest space possible. Hold the egg’s blunt end against the candler opening, creating a seal with your fingers. Slowly rotate the egg while examining the contents through the shell. Look for spider-web patterns of blood vessels radiating from the developing embryo. Clear eggs with no visible development indicate infertility.
Best Timing During Incubation
Day 7-10 provides the clearest fertility assessment for most chicken breeds. White eggs show blood vessel development by day 5, while brown eggs require day 7-8 for reliable results. Candling too early (days 1-4) may miss viable eggs that develop slowly. After day 14, growing embryos make fertility determination more challenging due to size.
Safety Tips and Precautions
Limit candling sessions to 30 seconds per egg to prevent overheating the developing embryo. Handle eggs gently and ensure your hands are clean before touching shells. Never candle eggs more than twice during incubation. Work in a warm room to minimize temperature shock, and return candled eggs to the incubator immediately to maintain consistent heat.
Conclusion
Your success with egg candling ultimately depends on choosing the right tool for your specific needs and flock size. Whether you’re investing in a premium Brinsea OvaView for commercial operations or starting with a budget-friendly generic model for your backyard chickens you’ll save valuable time and resources by identifying viable eggs early in the incubation process.
Remember that proper technique matters just as much as having quality equipment. Take time to practice your candling skills in the right conditions and you’ll quickly become proficient at spotting those telltale spider-web blood vessels that indicate successful development.
The investment in a quality egg candler pays for itself through improved hatch rates and more efficient use of your incubator space. You’ll transform from guessing about fertility to making informed decisions that enhance your breeding program’s success.
Frequently Asked Questions
What is egg candling and why is it important?
Egg candling is a method of shining light through an eggshell to assess fertility and embryo development during incubation. It’s important because it allows farmers to identify viable eggs early in the process, saving time, electricity, and incubator space. Instead of waiting 21 days to see if eggs hatch, candling reveals developing embryos and blood vessels within the first week of incubation.
When is the best time to candle eggs?
The optimal time for candling eggs is between days 7-10 of incubation. For white eggs, blood vessel development can typically be seen by day 4-6, while brown eggs usually show clear development by day 6-8. Duck and goose eggs may require waiting until day 7 for clear visibility of development patterns.
What are the signs of a fertile versus infertile egg when candling?
Fertile eggs display spider-web patterns of blood vessels radiating from the developing embryo, creating a network-like appearance. Infertile eggs remain clear with no visible development or may show a blood ring. The fertile egg will also have a dark spot indicating the growing embryo, while infertile eggs lack these developmental signs.
