As a backyard chicken keeper for over 5 years now, one of the most common questions folks ask me is about the timing of egg production. Whether you’re a seasoned chicken owner or just getting started with your first flock, understanding the egg-laying process helps set realistic expectations. In this article, I’ll crack open all the details about how long it takes for a chicken to lay a single egg, what affects their laying schedule, and how to optimize your flock’s egg production.
Quick Answer
On average, it takes a chicken approximately 24-26 hours to form and lay a single egg. This process begins shortly after the previous egg is laid and continues in a fairly consistent cycle throughout a hen’s prime laying years.
The Complete Egg-Making Process
The journey from ovary to nest box is quite fascinating! Here’s what happens during those 24-26 hours
- Yolk Release (Ovulation): Minutes after laying her previous egg, the hen’s ovary releases a new yolk
- Egg White Formation: As the yolk travels through the oviduct, egg whites (albumen) are added
- Membrane Development: Protective membranes form around the developing egg
- Shell Formation: The shell develops – this takes the longest time, about 20 hours
- Pigment Addition: Color is added to the shell (depending on breed)
- Bloom Coating: A protective coating called the “bloom” is applied
- Laying: Finally, the completed egg moves to the vent and is laid, typically blunt end first
This entire process repeats almost daily during a hen’s productive laying period. The reason hens don’t lay exactly one egg every 24 hours is because this process takes slightly longer than a day, causing each egg to be laid a bit later than the previous one.
When Do Chickens Start Laying Their First Egg?
If you’re starting with baby chicks, you’ll need some patience before collecting your first farm-fresh eggs. Here’s what to expect:
- Average Age: Most pullets (young hens) begin laying their first egg around 5-6 months of age
- Early Layers: Some breeds may start as early as 16-18 weeks (4 months)
- Late Bloomers: Other breeds might take up to 28-32 weeks (8 months)
The majority of chickens will lay their first egg between 20-24 weeks. If you purchase chicks in spring (March-May), you’ll likely start collecting eggs between August and October.
Breed Matters: Fast vs. Slow Layers
Just like people, different chicken breeds develop at different rates. Some breeds are known to mature quickly and start laying earlier:
- Austra Whites
- New Hampshire Reds
- Black Australorps
- Plymouth Rocks (all color varieties)
- Leghorns (Brown, Exchequer, White)
- Golden Buffs
Breeds that typically take longer to mature include:
- Cochins
- Polish
- Brahmas
- Silkies
Factors That Influence Egg Production Timelines
While the basic 24-26 hour egg formation process is fairly consistent, several factors can affect how frequently your chickens lay:
Age
- Young Hens (20-30 weeks): Highest laying frequency
- Prime Layers (1-2 years): Consistent production
- Older Hens (3+ years): Gradually decreasing egg production
Season
- Spring/Summer: Peak laying season with 14-16 hours of daylight
- Fall: Declining egg production as daylight hours decrease
- Winter: Minimal egg production unless supplemental lighting is provided
Nutrition
- Insufficient protein can slow egg production
- Calcium deficiency affects shell quality and laying frequency
- Overall balanced nutrition supports optimal laying
Environment
- Stress from predators can halt laying
- Extreme temperatures (hot or cold) affect production
- Overcrowding reduces laying frequency
Individual Hen Factors
- Health issues can pause egg production
- Broodiness (desire to hatch eggs) stops laying temporarily
- Molting (annual feather replacement) pauses egg-laying for 1-2 months
The Daily Egg Laying Schedule
An interesting fact about chicken egg-laying is that hens typically lay their eggs earlier in the day, usually within the first 6 hours after sunrise. Due to the 24-26 hour formation cycle, a hen will lay her egg approximately 2 hours later each successive day.
For example:
- Monday: Hen lays at 7 AM
- Tuesday: Same hen lays around 9 AM
- Wednesday: Same hen lays around 11 AM
- And so on…
Eventually, the timing gets too late in the day for the hen’s body to begin the process again (hens don’t lay at night when they’re sleeping). This results in the hen skipping a day before starting the cycle again the next morning.
This is why most chickens don’t lay exactly one egg every day – the natural cycle includes occasional skip days.
Signs Your Hen is About to Lay
With a bit of observation, you can often tell when your hen is preparing to lay an egg:
- Increased interest in nest boxes
- Restlessness and clucking
- “Squatting” behavior when approached
- Vent area appears larger, redder, and more moist
- Decreased appetite just before and during laying
Tips for Optimizing Your Flock’s Egg Production
If you’re hoping to maximize egg production from your backyard chickens, here are some practical tips:
Choose Productive Breeds
Select breeds known for excellent laying ability like Australorps, Orpingtons, or Leghorns if egg production is your primary goal.
Nutrition Matters
- Provide high-quality layer feed (16-18% protein)
- Offer free access to calcium supplements like oyster shell
- Follow the 90/10 rule: 90% complete layer feed, 10% treats and supplements
- Ensure clean, fresh water is always available
Create an Ideal Environment
- Provide comfortable nest boxes (1 box per 4 hens)
- Keep stress to a minimum
- Ensure adequate space (minimum 4 square feet per bird)
- Protect from extreme temperatures
Lighting
During winter months, provide supplemental lighting to maintain 14-16 hours of “daylight” if continuous egg production is desired. However, many chicken keepers allow their hens a natural winter break.
Common Questions About Chicken Egg Laying
Do chickens lay eggs every day?
Healthy young hens in their prime laying period can lay 5-6 eggs per week on average. Due to the 24-26 hour egg formation cycle, most hens naturally skip at least one day per week.
Do hens lay eggs in winter?
Egg production naturally decreases in winter due to reduced daylight hours. Hens need about 14-16 hours of light to stimulate maximum egg production. Without supplemental lighting, many hens will lay fewer eggs or take a complete break during the darkest winter months.
Is it cheaper to raise chickens or buy eggs?
Honestly, raising chickens is generally not cheaper than buying eggs, especially when considering initial setup costs. However, the quality of fresh backyard eggs and the joy of raising chickens makes it worthwhile for many of us!
What affects egg shell quality?
Diet (especially calcium intake), age of the hen, and stress all impact shell quality. Older hens tend to lay eggs with thinner shells, while calcium-deficient diets can lead to soft or misshapen eggs.
When to Be Concerned
While variations in laying patterns are normal, here are some signs that might indicate a problem:
- A previously consistent hen stops laying entirely for over a week
- Egg shells are very thin or eggs have irregular shapes
- Your hen seems lethargic or is losing weight
- There are no signs of approaching lay (changes in vent appearance, nesting behaviors)
The Verdict: Worth the Wait!
Whether you’re waiting for your pullets to lay their first egg or patiently accepting the natural rhythms of your mature hens, understanding the egg-laying process helps set realistic expectations. The 24-26 hours it takes for a chicken to create each perfect little package of nutrition is truly remarkable!
In my experience with my small flock of 8 hens, I’ve found that each chicken develops her own unique laying pattern. My Black Australorp started laying at just 18 weeks, while my Brahma took nearly 7 months before producing her first egg. Now they provide our family with about 40-45 eggs weekly during peak season – more than enough for our needs plus some to share with neighbors.
Remember that backyard chicken keeping is about more than just egg production. These fascinating creatures provide entertainment, pest control, compost for gardens, and a connection to our food source that’s increasingly rare in today’s world.

Do hens lay eggs in the winter?
The hen’s ovulation is stimulated by the length of the day. Maximum egg production is reached during summer days with 16 hours of daylight. Egg production may continue during the spring, fall, and winter when artificial light is supplemented to provide 14 -16 hours of light. Using a timer and a 60-watt incandescent bulb, add light to the morning and late afternoon but allow hens to naturally roost in the evenings with the setting sun.
When do hens begin to lay eggs?
During ideal day length (14-16 hours of light) and with adequate nutrition, housing, and management, hens (depending on breed) should begin producing eggs when they are18- 22 weeks old.
