Switch chickens to layer feed at around 18 weeks of age, when they begin to lay eggs, to ensure optimal nutrition for egg production.
Switching chickens to layer feed at the right time is crucial for egg production and flock health. The ideal transition occurs between 18-20 weeks or when you spot the first egg. Layer feed contains extra calcium for strong eggshells and proper nutrition for laying hens.
Understanding Chicken Feed Stages
Chickens require different feeds throughout their life cycle to meet changing nutritional needs:
| Feed Type | Age Range | Protein Content | Key Features |
|---|---|---|---|
| Starter Feed | 0-6 weeks | 18-24% | High protein for rapid growth |
| Grower Feed | 6-18 weeks | 16-18% | Supports steady development |
| Layer Feed | 18+ weeks | 16-18% | Added calcium for egg production |
Why Timing Matters
Switching too early can cause kidney damage from excess calcium. Waiting too long may lead to weak eggshells. Watch for these signs your pullets are ready:
- Reddening combs and wattles
- Squatting behavior when approached
- Exploring nesting boxes
- Increased vocalization
Breed-Specific Laying Timelines
Different breeds start laying at varying ages. Here’s when popular breeds typically begin egg production:
Early Layers (16-20 weeks)
- Leghorns
- Rhode Island Reds
- Sex Links
Average Layers (20-24 weeks)
- Plymouth Rocks
- Orpingtons
- Australorps
Late Layers (24-28 weeks)
- Silkies
- Cochins
- Some heritage breeds

Transitioning to Layer Feed
Make the switch gradually over 7-10 days to prevent digestive upset:
- Days 1-3: 75% grower feed, 25% layer feed
- Days 4-6: 50% grower feed, 50% layer feed
- Days 7-9: 25% grower feed, 75% layer feed
- Day 10: 100% layer feed
Supplemental Calcium Options
Even with layer feed, many hens benefit from additional calcium sources:
- Oyster shell (offered free-choice)
- Crushed eggshells (baked first to prevent egg-eating)
- Limestone grit
Common Feeding Mistakes to Avoid
1. Switching Too Early
Premature layer feed can cause kidney damage in developing pullets. Wait until at least 16 weeks for early-maturing breeds.
2. Ignoring Protein Needs
During molt or stress, hens may need supplemental protein. Consider strategies to prevent feather pecking during high-protein needs.
3. Unlimited Treats
Treats should never exceed 10% of daily intake. Overfeeding snacks can lead to nutritional imbalances.
Alternative Feeding Approaches
Some poultry keepers prefer alternative methods:
Flock Raiser Feed
This all-purpose feed works for mixed flocks when supplemented with oyster shell for layers. According to Purina’s research, this can be an effective approach.
Whole Grain Feeding
Some homesteaders use a base of whole grains with separate protein and calcium supplements. This requires careful balancing.
Special Considerations
Mixed Age Flocks
For flocks with layers and younger birds:
- Feed layer ration to all
- Provide separate grower feed for juveniles
- Or use flock raiser with oyster shell on the side
Non-Laying Hens
Older hens or those not laying (like some in winter) may do better on maintenance feed rather than layer ration.
Monitoring Your Flock’s Health
After switching to layer feed, watch for:
- Strong eggshells (no thin or soft shells)
- Consistent egg production
- Healthy weight maintenance
- Bright eyes and clean feathers

Seasonal Adjustments
Layer feed requirements change with seasons:
Summer
Hens may eat less in heat. Ensure fresh water always available.
Winter
Increase feed slightly to help maintain body heat. Consider scratch grains for energy.
Storage and Freshness
Proper feed storage maintains nutritional quality:
- Store in airtight containers
- Keep in cool, dry place
- Use within 4 weeks of opening
- Check for mold or pests
By following these guidelines and observing your flock, you’ll ensure a smooth transition to layer feed that supports optimal egg production and chicken health.
