Do Chickens Need Sunlight To Lay Eggs?

Chickens are interesting birds that are well-known for their capacity to lay eggs. Did you realize, though, that sunshine is crucial to the success of their egg-laying process? In other words, chickens are photoperiodic, meaning they react to the length of daylight.

Consequently, they need a specific amount of sunshine to balance their hormones and produce eggs. This article will discuss the importance of exposing hens to sunshine and how it affects their ability to lay eggs. So, let’s explore the lives of hens and find out how they use light to their advantage. 

The Role Of Light And Its Impact on Chicken Egg Production 

  • Duration of a Day 

It is well-documented that the amount of sunlight available to hens has a direct effect on their ability to lay eggs. Egg production in chickens needs a particular daily amount of light, so if they do not get enough light, egg production may slow or halt altogether. 

  • Reactions in Hormones 

It has been found that exposing hens to bright light can cause them to release hormones that regulate egg production. Light cycles in the wild can affect a hen’s ability to lay eggs. However, the type and quantity of artificial light that hens are subjected to in captivity can have an effect on their ability to lay eggs. 

  • Keeps the Body’s Natural Rhythms In Check 

The duration of daylight influences chickens’ internal clocks, making them photoperiodic creatures. Maintaining this pattern and producing eggs at regular intervals is facilitated by consistent exposure to light. 

  • Increase egg production: 

There is evidence to suggest that hens housed in brighter environments produce more eggs than their dark counterparts. 

  • Enhances the Quality of Eggs:

Natural sunlight enhances egg quality by nourishing laying hens with vitamins and minerals. 

  • Prompts Sexual maturity: 

Light is also crucial for hens to reach sexual maturity and begin laying eggs because it stimulates the production of reproductive hormones. 

  • Promotes Physical and Mental Health:

Chickens benefit from exposure to natural light in ways other than increased egg production. It’s good for their immune system that helps keep them from being stressed out or sick.

The Effect Of Sunlight On Egg Production

  • Making Vitamin D 

Vitamin D from the sun is crucial to a hen’s well-being. Strong bones & eggshells require the mineral calcium, which is best absorbed with the help of vitamin D. Chickens may not create enough vitamin D if they are not exposed to adequate sunlight, which can result in brittle bones & shells and a decline in egg production. 

  • Physical Health

Chickens’ bodies benefit greatly from time spent in the sun. Chickens’ egg production may increase as a result of exposure to sunshine since it boosts the birds’ immunity and general health. The heat from the sun can also aid in keeping the chickens at a comfortable temperature. 

The Effect of Artificial Light On Egg Production

  • Synthetic Light Bikes 

Egg production in hens can be negatively impacted by artificial light cycles, which is common in captive environments. Egg production in chickens can be affected by factors such as the duration and strength of artificial lighting. 

  • Using Energy Efficiently 

It is possible to produce eggs without using any natural light at all by carefully manipulating the intensity of artificial light. Besides providing the chickens with a reliable light source, this can also help to lower the price of egg production. 


To sum up, hens don’t have to be in direct sunlight to produce eggs, but they do need access to natural light. Chickens’ ability to lay eggs can be affected by factors such as the amount of time they spend in the sun, the quality & intensity of the light they are exposed to, and the number of vitamins like vitamin D.

Eggs need a certain amount of light, which can be provided either by natural sunshine or artificial light. When it comes down to it, chickens’ exposure to different kinds of light will be determined by their own unique requirements and environmental conditions.
