Reasons for Supplemental Lighting
Promoting egg production
Supplemental lighting is often used to promote egg production in hens during the winter months when natural daylight is limited. By providing artificial light, the hens’ reproductive systems are stimulated, encouraging them to lay more eggs. This is particularly important for commercial egg production, where maximizing egg output is crucial for profitability. Additionally, supplemental lighting can help maintain a consistent supply of eggs to meet consumer demand even during the colder months.
Maintaining egg size and quality
Without adequate lighting, hens may reduce or cease egg production altogether during the winter. When egg production resumes, there is a risk of irregular egg sizes and reduced quality. Supplemental lighting ensures that hens continue to produce eggs of optimal size and quality throughout the year. This consistency is essential for meeting consumer expectations and maintaining a reputable brand.
Reducing broodiness
Broodiness, the instinctive behavior in hens to incubate eggs, can disrupt egg production. By providing supplemental lighting, the natural responses of hens to increasing day length are mimicked, reducing broodiness. This allows the hens to focus more on egg production rather than nest building and incubation, resulting in higher egg yields.
Extending laying season
Supplemental lighting also extends the laying season for hens. By providing additional light in the morning or evening, hens perceive longer days, tricking their biological clocks into continuing egg production. This is especially beneficial for small-scale chicken keepers who rely on a consistent supply of eggs for personal consumption or local sale.
Lighting Requirements for Egg Production
Understanding the natural response to light
Hens’ reproductive systems are sensitive to changes in the duration and intensity of light. As days lengthen in spring, a hormone called melatonin is suppressed, triggering an increase in egg production. However, during the winter months, the natural decrease in light can hinder this process. Supplemental lighting aims to replicate the natural response to light, thus stimulating egg production.
Optimal lighting duration and intensity
To effectively promote egg production, the duration and intensity of supplemental lighting need to align with hens’ natural response to light. Generally, providing 14-16 hours of light per day is recommended for maximum egg production. The intensity of the light should be approximately 2-3 foot-candles at hen eye level. It is important to note that excessive light can disrupt the hens’ sleep-wake cycle and may have adverse effects on their health.
Managing light schedules
Managing the light schedules for hens requires careful planning and consistency. Artificial lighting should be provided at regular intervals to replicate natural daylight cycles. It is advisable to gradually increase the duration of artificial lighting during the winter months and decrease it during the summer to mimic seasonal changes. Additionally, sudden changes in lighting schedules should be avoided as they can cause stress in the hens and disrupt egg production.
Types of Lighting Systems
Natural lighting
Natural lighting, provided by windows or openings in the chicken coop, is the ideal and most cost-effective lighting system for hens. It allows the hens to experience natural dawn and dusk, which promotes their overall well-being and stimulates egg production. However, in certain regions where daylight is limited during the winter, natural lighting alone may not be sufficient for optimal egg production.
Artificial lighting
Artificial lighting systems are commonly used to supplement natural lighting and ensure consistent egg production. These systems typically use electric lamps that emit light in the blue spectrum, resembling natural daylight. They can be easily controlled to provide the desired duration and intensity of light. However, it is important to choose energy-efficient bulbs and consider the potential risks associated with electrical lighting systems.
Combination systems
Combination lighting systems utilize both natural and artificial lighting sources to provide a balanced lighting environment for hens. This approach combines the benefits of natural light with the consistency and control of artificial lighting. By integrating both types of lighting, hens can experience the natural changes in daylight while still receiving supplemental light during the darker periods of the day.
