3 Factors Affecting Egg Quality and the 1 Easiest to Improve

3 Factors Affecting Egg Quality and the 1 Easiest to Improve

Several critical factors affect egg quality - and while some factors are more difficult to resolve, one stands out as the easiest win to improve the bottom line for commercial producers.  

Egg quality refers to several characteristics including the integrity and cleanliness of the shell, the viscosity of the albumen (egg white), and the firmness and color of the yolk. These factors and are crucial for the viability of embryos in hatcheries and the sensory quality of table eggs - but if an egg breaks before it reaches the consumer or processing facility, these factors are essentially irrelevant. 

The fact is: reducing egg breakage rates is one of the most profitable areas of improvement for producers. Farms and producers focusing on breakage reduction and deploying innovative solutions like CracklessEgg have the upper hand in boosting egg integrity and quality rates.

Importance of Egg Quality

In the commercial poultry industry, egg quality is not merely about the appearance of the egg; it's a crucial indicator of the health of hens, the effectiveness of farm management practices, and the financial viability of the operation. High-quality eggs lead to superior hatchability, higher consumer satisfaction, and increased profitability.

High-quality eggs can withstand the rigors of handling and transport, are less susceptible to contamination, and have higher nutritional values, which are all crucial for consumer satisfaction. In the hatchery, the quality of eggs affects the development and health of chicks, which are critical parameters for the success of poultry farms.


Factors Affecting Egg Quality

Nutritional Factors

Nutrition plays a pivotal role in the quality of eggs. Hens require a balanced diet rich in calcium, phosphorus, and essential vitamins to produce strong, healthy eggs. The lack of any essential nutrient can lead to poor shell quality and weak embryos. For example, a deficiency in vitamin D can result in thin shells, while insufficient vitamin A can cause poor yolk quality.

Nutritional factors are an important consideration affecting both the marketability and usability of the eggs.

Environmental Factors

The living conditions of hens significantly impact egg quality. Factors such as ambient temperature, humidity, and lighting must be carefully controlled. High temperatures can cause heat stress which leads to a decrease in egg production and quality. Similarly, improper humidity levels can affect the moisture content of eggs, making them prone to bacterial growth.

As most farmers will tell you, stressful conditions, such as extreme temperatures or poor ventilation, can adversely affect hen health and egg quality.

Egg Handling

The way eggs are handled from the moment they are laid until they reach the consumer can also affect their quality. It is a critical process that requires meticulous attention to detail to ensure egg quality is maintained. 

By understanding the risks at each stage and implementing effective mitigation strategies, poultry producers can significantly enhance the quality and safety of their eggs, thereby satisfying consumers and improving profitability. Proper handling techniques reduce the risk of contamination and physical damage. This includes gentle collection practices, immediate cooling, and careful packing.


Reducing Egg Breakage During Egg Handling as a Quality Factor

Egg Handling: The Key to Maintaining Optimal Egg Quality

The quality of eggs is directly influenced by the care taken during their handling from the moment they are laid to when they are packaged for sale. Each step in this process requires meticulous attention to detail to prevent damage and ensure the eggs reach consumers in perfect condition. 

Point of Lay

The journey of an egg starts in the hen house, where hens lay eggs in designated nesting boxes. It's essential that these areas are clean and accessible, encouraging hens to use them consistently, which helps keep the eggs clean and reduces the chance of damage. Prompt collection of eggs after they are laid minimizes the risk of them being stepped on or pecked by other hens.

Initial Collection

The initial collection of eggs, whether done manually or via automated systems, sets the stage for their quality. Gentle handling is crucial; automated systems should be calibrated to handle eggs delicately, avoiding pressure that can cause cracks. Staff trained in careful manual collection can ensure that eggs are not dropped or mishandled during this sensitive phase.

Transportation to Processing Area

Once collected, eggs must be transported to a processing area. This step involves moving the eggs from the laying area to a facility where they will be cleaned and inspected. The use of cushioned transport containers helps in absorbing any shocks or vibrations during transit, and maintaining a controlled environment prevents temperature and humidity fluctuations that can affect the egg quality.

Washing and Cleaning

Upon arrival at the processing facility, eggs are washed to remove any contaminants. Using the right temperature and pressure for the wash water, along with approved egg washing solutions, ensures that eggs are cleaned without compromising the integrity of their shells. This cleaning process is crucial for preventing bacterial contamination and ensuring the eggs are safe for consumption.

Candling and Inspection

After cleaning, eggs undergo candling, a method that uses light to inspect the internal and external quality of each egg. This stage is vital for identifying any internal defects or issues with the eggshell that might not be visible externally. High-quality candling equipment and well-trained personnel can accurately assess the quality, ensuring that only the best eggs move forward in the process.


Grading sorts eggs by size and quality, which is crucial for meeting consumer expectations and regulatory standards. Automated grading systems help ensure consistency and accuracy in this process. Regular equipment calibration is essential to maintain reliability and prevent errors that could lead to misgraded eggs reaching the market.


Packaging is the final defense line in protecting eggs from damage. Using shock-absorbent materials and designing packaging that supports the eggs securely minimizes the risk of breakage. Automated packaging systems that handle eggs gently can significantly enhance the efficiency of this stage while maintaining high standards of quality.

Storage Pre-Transport

Proper storage before transportation to retail locations involves maintaining controlled temperature and humidity levels to preserve egg quality. Strategic stacking and storage protocols prevent overstacking, which can cause breakage and compromise egg integrity.

Transportation to Retailers

The final transportation of eggs to retailers must be managed carefully to avoid environmental stressors such as abrupt temperature changes and physical jolts. Refrigerated trucks and carefully planned routes that minimize travel time and vibrations are essential components of this stage.


How to Reduce Quality Loss during Egg Handling 

Reducing egg breakage during handling is crucial as it directly impacts profitability. Innovations in packaging and automated handling systems have significantly decreased the rate of breakage in transit and storage - but these systems still need to be maintained and optimized to reduce egg cracking and breakage.
