The Ultimate Guide to Optimal Lighting Hours for Egg Production (Hint: 14 – 16 Hours)

Laying Chickens: Shedding Light on the Question of How Many Hours Light Do Chickens Need To Lay Eggs?

Hello, fellow chicken lovers.

Quick Answer: 14 to 16 Hours is the optimal lighting hours for egg production.
BUT there is so much more to know…

If you’ve ever wondered how many hours of daylight a chicken needs to produce one egg, or you were unaware that a chicken needs daylight to produce a chicken egg, then you’re not alone. Like many creatures, chickens are influenced by the changing seasons when it comes to egg production.

This article will explore the lighting requirements for egg-laying chickens during the year. Specifically, we will discover why we get fewer eggs in Winter and Summer and more in Spring and Autumn. Understanding these seasonal variations can help you optimize your chicken farming operation for consistent egg production.

A crucial aspect of poultry care that directly impacts egg production is the number of lighting hours for our feathered friends. I’m a farmer based in the challenging high country of Victoria, Australia; I’m no stranger to the importance of providing the best conditions for my backyard chickens. Whether you’re a seasoned poultry keeper or just starting your backyard flock, understanding the proper lighting set-up can significantly boost your egg yield/production.

I hope to make this easier for you than it was for me when I was starting my egg farm.

Winter: Short Days and Supplemental Lighting

In Winter, the days are shorter, and natural daylight hours can be as brief as 8-10 hours in some regions. This reduced daylight significantly impacts egg production because chickens require a minimum of 14-16 hours of light per day to lay just one egg and also to lay eggs consistently daily. Many farmers use supplemental lighting in the chicken coop to solve the issue of fewer eggs due to fewer daylight hours. By providing artificial light in the early morning and evening, you can extend your chickens’ “daylight” hours and maintain steady egg production throughout the winter.

Solar lighting with battery storage is a great way to increase light levels. The lights must be bright enough lumen to create strong enough light to imitate or replicate daylight. Solar may not always be the best option, but it worked well for me in Victoria, where I trialed this type of lighting. If you live in a colder area, solar panels may not receive enough sunlight to charge the batteries that power the lights, especially in areas with frequent cloud cover or snow. You may need other supplemental lighting forms to maintain egg production in such cases.

Summer: Lots of Natural Light

Summer brings long daylight hours, which is excellent news for egg-laying chickens and their owners. Chickens thrive with ample natural light; during this season, they typically receive 15-16 hours of daylight. This abundance of sunlight encourages regular egg production. However, it’s essential to ensure that the coop has adequate ventilation and shade, as extreme heat can be stressful for your birds and actually cause chickens to reduce the production of eggs. A chicken will falter in egg production after one moment of overheating (and/or under-eating).

Spring: Transitioning to Longer Days

In Spring, daylight hours increase, which signals a shift in the chickens’ egg-laying patterns. As the days lengthen, your hens will naturally lay more eggs. However, you should still monitor the daylight hours to ensure they get at least 14-16 hours of light each day. This transition can be an excellent time to reduce or eliminate supplemental lighting if you’ve been using it during the Winter. Again, ensure your hens are comfortable and have access to water and food high in protein.

Autumn: Maintaining Egg Production

As Autumn arrives, daylight hours start to decrease once again. To maintain consistent egg production, consider continuing with supplemental lighting in the coop during the evening hours. This extra light will help your chickens meet their daily light requirements, ensuring they produce eggs even as the days grow shorter. The same rules apply in regard to food and water.

How Many Hours of Daylight Do Chickens Need to Produce One Egg?

Chickens need approximately 14-16 hours of light daily to lay one egg. However, it’s important to note that breed, age, and overall health can also influence egg production. Some breeds have more prolific layers than others, and younger hens tend to lay more eggs than older ones. You will find more about this on my blog in other sections under the appropriate Categories.

Understanding the ‘seasonal variations’ in daylight hours and their impact on egg-laying chickens is crucial for successful egg production. You can maintain a steady supply of fresh eggs year-round by providing supplemental lighting during the winter and ensuring your chickens receive enough natural light during the other seasons. Remember that happy and healthy chickens are likelier to lay consistently, so ensure a comfortable and well-maintained environment.

The Science Behind Egg Production

Now, let’s examine the science behind egg production in pullets and hens. We will stick to discussing the impact of different seasons and offer practical tips to optimize your chicken coop’s lighting system.

Okay, so let’s shine some light on this topic and help you achieve your egg-laying goals while using the ‘Mediterranean climate’ as a guide; that’s the climate I have farmed in and have the most experience in. I also must mention we have occasional destructive winds on our property. I did say it was a challenging climate.

The Science Behind Lighting and Egg Production

As discussed above, chickens need 14 to 16 hours to use their bodies to produce and lay eggs. It’s very helpful to understand the biological mechanisms at play. Like many creatures, chickens have a circadian rhythm influenced by light exposure. We shall look at and explore a little on

1.1. Circadian Rhythm and Egg-Laying

As in most animals (including humans), Chickens’ circadian rhythm is a powerful force that regulates many biological functions, including egg-laying. By understanding the science behind circadian rhythm, you can take steps to improve egg production and keep your chickens healthy and happy.

The biological cycle follows a 24-hour pattern controlled by an internal “biological clock” that synchronizes bodily functions. In the case of egg-laying in chickens, circadian rhythms play a crucial role.

Easy explanation:

Light Sensitivity – Chickens are sensitive to light, especially natural daylight. The presence of light influences their behavior, including egg-laying.

Environmental Factors like temperature, nutrition, and stress can also affect egg-laying in chickens, but the circadian rhythm provides the baseline for their reproductive cycle.

Circadian rhythms in chickens are the internal biological clock that helps regulate when they lay eggs. The sensitivity to light and the pineal gland’s role in producing melatonin are key components of this process.

Circadian rhythm is a natural, internal process that regulates the sleep-wake cycle and other biological functions over a 24-hour period. It is controlled by a master clock in the brain, which is synchronized with the light-dark cycle of the environment.

Egg-laying in chickens is also regulated by circadian rhythm. Chickens are diurnal animals, meaning they are most active during the day. They typically lay eggs between 6 am and 11 am in the morning.

The science behind circadian rhythm and egg-laying in chickens is complex, but it can be simplified as follows:

• Light is the leading environmental cue that synchronizes the circadian clock in chickens.
• When chickens are exposed to light, their pineal gland produces less melatonin, a hormone that promotes sleep.
• Low levels of melatonin signal to the body that it is daytime, which triggers several physiological changes, including the release of hormones that stimulate egg production.
• Chickens need at least 14 to 16 hours of light daily to maintain optimal egg production.

 Do you want to improve egg production in your chickens?

Do this:

• Provide chickens with a minimum of 14 hours of light daily, preferably 16 hours.
• Use a timer to turn Solar lights on and off simultaneously each day. This will help to keep their circadian rhythm on track.
• Make sure your chickens have a dark place to sleep at night.
• Avoid exposing your chickens to bright lights at night.

Melatonin and Reproductive Hormones

Melatonin and reproductive hormones play a crucial role in egg-laying chickens. Here’s a simplified explanation:

1. Melatonin: Like humans, chickens also have a hormone called melatonin. Melatonin is usually associated with sleep in animals. In chickens, melatonin helps regulate their internal body clock. When days get shorter in the winter, chickens produce more melatonin, which signals their bodies that it’s time to rest and conserve energy. This reduced light exposure triggers changes in their reproductive hormones.
2. Reproductive Hormones: Egg-laying is controlled by a group of hormones. The main ones are:
   • Estrogen: This hormone is produced in a chicken’s ovaries and is essential for egg development.
   • Progesterone: It helps maintain the health of the reproductive system.
   • Luteinizing Hormone (LH): This hormone triggers ovulation, releasing eggs from the ovaries.
   • Follicle-Stimulating Hormone (FSH): FSH stimulates the development of egg follicles in the ovaries.

When the days get longer in Spring and Summer, melatonin production decreases. This signals the chicken’s body to release more reproductive hormones, which, in turn, leads to an increase in egg production.

So, in simple terms, melatonin regulates the chicken’s internal clock, and the balance of reproductive hormones controls when and how frequently they lay eggs. When the days are longer and brighter, they lay more eggs, and egg production decreases when it gets darker and colder.

Optimal Lighting Hours for Egg Production

Minimum Lighting Duration

Understanding the minimum lighting duration for egg-laying chickens is the first step for beginner chicken keepers. Chickens typically require a minimum of 14-16 hours of light daily to lay eggs consistently. Natural daylight hours fluctuate throughout the year, so it’s essential to supplement with artificial light, especially during the darker months of the year.

Extending Daylight Hours with Artificial Light

As the seasons change, so do daylight hours. To maintain peak egg production, consider extending daylight hours with artificial light. Set up a timer to add extra hours of light in the morning or evening, simulating natural daylight. This practice helps keep your chickens in a consistent laying routine.
