Twenty chickens can lay approximately 140 to 200 eggs per week, depending on factors like breed, age, and health.
If you’re raising backyard chickens, knowing their egg production is key. With 20 hens, you can expect 5-6 eggs daily (35-42 weekly). But many factors influence this number. Let’s break it down.
Egg Production Basics for 20 Chickens
On average, a healthy hen lays 200-300 eggs annually. This means:
- 200 eggs/year = 3-4 eggs/week per hen
- 250 eggs/year = 4-5 eggs/week per hen
- 300 eggs/year = 5-6 eggs/week per hen
For 20 chickens:
| Production Level | Daily Eggs | Weekly Eggs |
|---|---|---|
| Low (200 eggs/yr) | 3-4 | 21-28 |
| Medium (250 eggs/yr) | 4-5 | 28-35 |
| High (300 eggs/yr) | 5-6 | 35-42 |
Key Factors Affecting Egg Production
1. Breed Differences
Some top egg-laying breeds:
- Leghorns: 280-320 eggs/year
- Rhode Island Reds: 250-300 eggs/year
- Australorps: 250 eggs/year

2. Age of Hens
Peak production occurs between 6-18 months. After 2 years, egg production declines by 10-20% annually.
3. Daylight Hours
Chickens need 14-16 hours of light for maximum production. Many farmers use supplemental lighting in winter months.
4. Nutrition
A balanced layer feed with 16-18% protein is essential. Grit and calcium supplements help with eggshell formation.
5. Stress Factors
Predators, extreme weather, and overcrowding can reduce laying. Pecking order issues also impact production.
Seasonal Variations
Expect these patterns:
- Spring: Peak production (up to 6 eggs/day from 20 hens)
- Summer: Slight decrease due to heat
- Fall: Molting begins, production drops
- Winter: Lowest production (possibly 1-2 eggs/day)
Calculating Your Needs
Use this formula:
(Number of hens) × (Eggs/hen/day) = Daily production
Example: 20 hens × 0.7 eggs/day = 14 eggs/day
For more precise planning, consider:
- Your family’s weekly egg consumption
- Desired surplus for selling/gifting
- Expected seasonal variations
Maximizing Egg Production
Coop Management
Provide 1 nesting box per 4-5 hens. Keep bedding clean and dry.
Feeding Tips
Offer oyster shell free-choice. Ensure constant access to fresh water.
Health Monitoring
Watch for signs of parasites or illness that could reduce laying.
When Production Drops
If your 20 hens suddenly produce fewer eggs, check:
- Feed quality and quantity
- Water availability
- Predator stress
- Age of flock
- Recent weather changes

Egg Storage Tips
Unwashed eggs can stay fresh at room temperature for 2 weeks. Washed eggs should be refrigerated immediately. For long-term storage, consider freezing or water glassing.
Final Thoughts
While 20 chickens typically produce 35-42 eggs weekly, your actual yield will vary. By understanding these factors and managing your flock carefully, you can optimize egg production year-round.
