Is It Necessary To Provide Supplemental Lighting For Winter Egg Production?

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.
