To interpret the results of candling eggs accurately, carefully examine the interior of the egg for any signs of development or abnormalities using the Cool-Lite Tester and a dark or dimly lit room.
When you candle your eggs, hold the light source behind the egg, positioning it to illuminate the inside of the egg. You should be able to see through the eggshell to observe the contents. Look for signs of development such as veins, shadows, or movement within the egg.
Conversely, abnormalities may present as blood rings, floating dark spots, or an entirely clear egg. By scrutinizing the inside of the egg meticulously, you can make informed decisions about the viability and health of the embryo inside.
How to Interpret Candling Results
When examining candling results, we assess eggshell transparency, looking for consistency in light penetration.
We also focus on detecting signs of embryo development, such as veins or movement.
Moreover, we scrutinize the eggs for any defects like blood spots or hairline cracks.
Eggshell Transparency
Examining the eggshell transparency during candling reveals crucial insights into the viability and development stage of the embryo within.
- A clear, translucent eggshell with no visible veins or development indicates an infertile or non-viable egg.
- A dark, opaque eggshell with no visible veins or movement suggests a quitter egg that stopped developing.
- A partially dark eggshell with visible veins and movement indicates a developing embryo.
When we candle an egg, the degree of eggshell transparency allows us to see inside and assess the embryo's status accurately. If the embryo dies at any stage, the eggshell may show blood rings or dark streaks, indicating the need for removal from the incubator promptly.
Monitoring eggshell transparency is crucial for successful incubation outcomes.
Detecting Embryo Development
During candling, observing the presence of blood vessels and embryo development in the eggshell allows for the identification of viable embryos. Eggs showing clear signs of blood vessels and defined embryo structures are likely to be winners, indicating healthy development.
However, eggs that appear clear without any signs of development are probable yolkers, while those with a blood ring or dark streaking inside are likely quitters and shouldn't be returned to the incubator.
It's crucial to recheck any uncertain eggs on day 14, as handling eggs after this point can harm embryo development.
Identifying Defects
To accurately interpret candling results, one must carefully analyze the presence of blood rings, dark streaking, and visible signs of embryo development within the eggshell. When candling eggs, we should pay close attention to the following:
- Blood Rings or Dark Streaking: These indicate quitters that have stopped developing inside the egg.
- Clear Eggs: Eggs without any signs of development are yolkers and aren't fertile.
- Visible Veins and Blood Vessels: A good idea to candle, as they indicate a healthy network of blood vessels supporting embryo growth.
When to Start Candling
Assessing egg quality through candling is a crucial step before incubation begins. The first candling should occur between day 5 and day 7 to observe signs that the egg is developing properly. At this stage, the embryo should be visible as a dark spot with blood vessels radiating from it. It's essential to candle at this point to identify viable eggs for continued incubation.
Re-candling marked eggs around day 10 is necessary to remove any non-viable ones that may have stopped developing. This step helps maintain the ideal conditions for the healthy embryos.
Lastly, a critical candling at day 18 is crucial to ensure that no dead embryos remain before the lockdown period. This final check is essential to prevent potential issues during hatching.
