Natural Lighting for Egg-laying Hens

Importance of Natural Lighting

Natural lighting plays a vital role in the overall well-being and productivity of egg-laying hens. Exposure to natural light not only helps regulate their internal clock and promote healthier sleep cycles but also ensures the proper development of their reproductive systems. Natural light provides hens with crucial cues for egg production and helps maintain their natural physiological rhythms.

Effects of Natural Lighting on Egg-laying Hens

The effects of natural lighting on egg-laying hens are significant. Hens exposed to a natural lighting regime tend to have better egg production, superior egg quality, and reduced stress levels. Natural light stimulates the release of hormones that regulate ovarian function, resulting in increased egg production. Additionally, exposure to natural light has been linked to improved bone strength and overall health in hens.

Artificial Lighting for Egg-laying Hens

Reasons for Using Artificial Lighting

While natural lighting is essential, artificial lighting is often relied upon to supplement or replace natural light in egg-laying facilities. Artificial lighting allows producers to manipulate the hen’s photoperiod and extend the duration of light throughout the day. This can help stimulate egg production, especially during periods of limited natural light, such as winter months. Additionally, artificial lighting can be used to control and regulate the timing of egg-laying, promoting efficiency and maximized productivity.

Types of Artificial Lighting

There are various types of artificial lighting commonly used in egg-laying facilities. The most commonly used options include incandescent bulbs, fluorescent lights, LED lights, and photoperiod control systems. Each lighting type has its advantages and disadvantages, including factors such as energy efficiency, cost, and lifespan. Producers must choose the lighting system that best suits their specific needs and budget while providing the most appropriate conditions for their hens.

Factors to Consider when Establishing a Lighting Schedule

Age of the Hens

The age of the hens plays a crucial role in determining the lighting schedule. Young hens require different lighting conditions compared to mature hens. Gradual exposure to longer daylight hours during the rearing phase helps prepare young hens for optimal egg production later on. Once the hens reach maturity, the lighting schedule should be adjusted accordingly to meet their specific needs.


Seasonal changes affect natural lighting conditions and must be taken into account when establishing a lighting schedule. During winter months with shorter daylight hours, artificial lighting becomes essential to maintain optimal egg production. Conversely, during spring and summer when daylight hours are longer, minimal artificial lighting may be necessary.

Size of the Flock

The size of the flock plays a role in determining the optimal lighting schedule. Larger flocks may require a more intense lighting setup to ensure uniform illumination across the facility. Smaller flocks, on the other hand, may require less artificial light. It is essential to consider flock size to provide a comfortable lighting environment for all hens.

Physical Condition of the Hens

The physical condition of the hens should be considered when establishing a lighting schedule. Hens that are in poor health or recovering from an illness may require different lighting conditions to support their recovery process. Adjustments to the lighting schedule may be necessary to accommodate their specific needs and ensure their well-being.

Recommended Lighting Schedule for Egg-laying Hens

Pre-Laying Phase

During the pre-laying phase, young hens should be gradually exposed to increasing daylight hours. Start with 12-14 hours of light per day and gradually increase it to 16 hours by the time they reach maturity. This helps stimulate their reproductive systems and prepares them for optimal egg production.

Peak Laying Phase

Once hens reach their peak laying phase, provide a consistent lighting schedule of 16 hours of light per day. This ensures hens receive sufficient light to maintain their reproductive cycles and maximize egg production. Adjustments may need to be made according to factors such as flock size and season.

Post-Laying Phase

During the post-laying phase, gradually reduce the lighting duration back to 12-14 hours per day. This allows the hens to have a period of darkness to rest and recover, which contributes to their overall well-being. It is important to ensure a smooth transition to avoid causing stress to the hens.

Effects of Lighting Schedule on Egg Production

Optimal Egg Production

A well-managed lighting schedule has a direct impact on egg production. Providing hens with the appropriate lighting conditions stimulates their reproductive systems and promotes consistent egg-laying. By maintaining a consistent lighting schedule, producers can expect higher egg production rates, improved egg quality, and more reliable egg sizes.

Stress and Egg Production

Inadequate or inconsistent lighting schedules can result in increased stress levels among hens, which can negatively impact egg production. Hens that experience irregular lighting patterns may become stressed, leading to decreased egg production and potential health issues. A stable and reliable lighting schedule helps minimize stress levels, ensuring optimal egg production and the overall well-being of the hens.

Impact of Lighting Schedule on Hen Welfare

Physical Health

A well-regulated lighting schedule positively affects the physical health of egg-laying hens. Natural and artificial lighting play a role in maintaining optimal bone density, reducing the risk of fractures or weak bones. Proper lighting also promotes balanced hormonal activity and supports overall reproductive health.

Behavioral Patterns

Lighting schedules significantly influence the behavioral patterns of egg-laying hens. Consistent lighting conditions contribute to a more stable environment, reducing stress levels and promoting natural behaviors. Hens exposed to regular lighting schedules are more likely to exhibit healthy social interactions, forage, and engage in natural egg-laying behaviors.

Mortality Rate

Proper lighting schedules can impact the mortality rate among egg-laying hens. Inconsistent or inadequate lighting conditions may lead to increased stress levels, which can compromise the immune system and increase susceptibility to diseases. A well-managed lighting schedule contributes to a healthier environment, reducing the mortality rate among hens.

Considerations for Alternative Lighting Methods

Free-range Production

In free-range production systems, hens have access to natural lighting throughout the day. However, in specific geographic locations or during certain seasons, supplemental artificial lighting may still be necessary to maintain consistent lighting conditions. Monitoring natural light levels and adjusting artificial lighting accordingly is crucial for optimal egg production in free-range systems.

Organic Production

Organic production systems emphasize natural and organic practices, which includes providing hens with access to natural light. However, when natural lighting is insufficient, producers may need to employ artificial lighting methods to maintain consistent and appropriate lighting conditions. Careful consideration must be given to the lighting schedule, ensuring it adheres to organic production standards.

Cage-free Production

Cage-free systems offer hens more space to move and behave naturally. Natural daylight is provided in these systems, but artificial lighting may also be used to supplement or regulate lighting conditions. Monitoring the lighting schedule and adjusting when necessary is crucial to maximize egg production and provide optimal conditions for hens in cage-free production systems.

Monitoring and Adjusting Lighting Schedule

Regular Evaluation

Regular evaluation of the lighting schedule is essential to ensure it remains optimal for hens. Producers should monitor egg production rates, egg quality, and the overall health and behavior of the hens. By closely observing these factors, any necessary adjustments to the lighting schedule can be made to meet the specific needs of the flock.
