Raising chickens for eggs is a rewarding experience, but many backyard keepers face the same challenge: egg production drops as daylight hours decrease in fall and winter. Chickens are sensitive to day length, and shorter days signal their bodies to slow or stop laying. Luckily, modern technology offers a simple solution. Automated evening lighting can extend the productive season, keeping your flock laying when you need eggs most. Here’s how to use this strategy effectively and safely.
We’ve mapped out exactly how to mount your external solar panel at the optimal angle to capture maximum daylight. Feel free to check out our breakdown of the best solar hen house lighting kits to upgrade your backyard setup this weekend.
Why Chickens Need Light To Lay Eggs
Chickens are naturally tuned to the sun. Their internal clocks respond to the amount of light they receive each day. For most breeds, 14-16 hours of light signals that it’s time to lay. When days get shorter, their bodies rest, often leading to fewer eggs or even a complete pause.
Without intervention, you might see egg production drop by 50% or more from late autumn through early spring. For those who rely on a steady supply, this can be frustrating.
How Automated Evening Lighting Works
Automated lighting systems use timers to control when lights turn on and off in your coop. They add extra hours of light in the evening, “tricking” hens into thinking days are still long. This helps maintain consistent egg production.
Here’s a simple example:
- In December, natural daylight may last only 9 hours.
- Automated lighting adds 5-7 hours in the evening.
- Total light exposure reaches the 14-16 hour target.
A basic setup includes:
- LED or fluorescent lights (energy efficient, bright enough for reading)
- Timer or smart plug (to automate on/off cycles)
- Properly installed wiring and fixtures, safe from moisture and pecking
Setting Up Your Lighting System
Choosing The Right Lights
Use LED bulbs with a warm white color (2700-3000K). These are safe, efficient, and mimic sunlight well. Avoid bulbs that flicker, as chickens see flicker more than humans and it can stress them.
Placement And Coverage
Hang lights overhead, out of reach of pecking. One 9-watt LED bulb (60-watt equivalent) can cover a small coop (up to 50 square feet). For larger coops, use multiple bulbs.
Using Timers
Set your timer to turn lights on before sunset and off after your desired “day length” is reached. For example:
- Natural sunset: 5:00 PM
- Timer: 5:00 PM ON, 10:00 PM OFF (adding 5 hours)
Never leave lights on all night—chickens need a dark period for proper rest.
Comparing Common Light Sources
Here’s how different lighting options compare:
| Type | Efficiency | Heat Output | Lifespan |
|---|---|---|---|
| LED | High | Low | 25,000+ hrs |
| Fluorescent | Medium | Low | 7,000-15,000 hrs |
| Incandescent | Low | High | 1,000 hrs |
LEDs are best for most backyard coops.
Key Tips For Success
- Start gradually: Add 30 minutes of light every few days, not all at once. Sudden changes can stress hens.
- Check light intensity: Aim for 10-20 lux at chicken level (enough to read a newspaper comfortably).
- Maintain a natural rhythm: Always provide 8 hours of darkness so chickens can sleep.
Many beginners overlook the importance of gradual adjustment and the need for a true dark period. Skipping these steps can lead to health issues or even permanent laying problems.
Risks And Common Mistakes
While automated lighting is safe when used properly, there are pitfalls to avoid:
- Too much light: More than 16 hours can cause stress, feather pecking, or lower immunity.
- No darkness: Constant light disrupts sleep, leading to poor health.
- Old or unsafe wiring: Faulty installations are a fire risk.
- Ignoring breed differences: Some breeds lay better in winter naturally. Over-lighting hardy breeds is unnecessary.
Always follow safety guidelines and monitor your flock’s behavior. If you notice aggression, stress, or sudden drops in laying, check your lighting schedule and coop environment.
How Much Can Lighting Extend Egg Production?
Data from studies and farmer reports show that automated lighting can extend laying by 2-4 months each year. For example, a flock that stops in October may keep producing until February or March with proper lighting.
Here’s a comparison of average monthly egg counts per hen with and without extra lighting:
| Month | Without Lighting | With Lighting |
|---|---|---|
| November | 6 eggs | 18 eggs |
| December | 4 eggs | 17 eggs |
| January | 5 eggs | 16 eggs |
| February | 8 eggs | 18 eggs |
This can make a big difference for small flocks and home egg supply.

Cost And Energy Use
Many people worry about electricity costs, but LED lighting is very efficient. For a small coop, running one 9-watt bulb for 6 hours nightly uses about 1.6 kWh per month—less than a dollar in most areas.
Here’s a quick look at estimated monthly costs for different bulbs:
| Bulb Type | Watts | Monthly Cost* |
|---|---|---|
| LED | 9 | $0.20 |
| Fluorescent | 13 | $0.30 |
| Incandescent | 60 | $1.40 |
*Assumes 6 hours per night at $0. 14/kWh.
Is Automated Lighting Right For Your Flock?
Automated evening lighting is a proven way to extend egg laying seasons for most backyard chickens. However, it’s not always necessary for rare breeds or if you prefer giving hens a full winter break. If you want steady eggs year-round, this is the most reliable method.

Frequently Asked Questions
How Many Hours Of Light Do Chickens Need To Lay Eggs?
Chickens need about 14-16 hours of light each day to maintain regular egg laying. Less than 12 hours usually leads to a drop in production.
Can I Use Any Type Of Bulb In The Coop?
Not all bulbs are suitable. LED bulbs are best because they’re efficient, safe, and provide steady light without flicker. Avoid incandescent bulbs—they use more power and can get too hot.
Is It Safe To Leave Lights On All Night?
No, chickens must have at least 8 hours of darkness for healthy sleep. Never run lights all night.
Will Lighting Stress My Hens?
Properly set up, automated lighting won’t stress hens. Stress happens if you use too much light or skip dark periods. Add light gradually and always allow for rest.
When Should I Start Using Extra Lighting?
Begin adding light in early fall, as days shorten below 14 hours. Increase the artificial light by 30 minutes every few days to reach your target day length.
With a little planning and the right setup, automated evening lighting can help you enjoy a steady supply of fresh eggs throughout the coldest months of the year.
