While high-quality layer feed provides most of what chickens need, specific situations call for targeted supplementation. This guide helps you understand when supplements are beneficial and which ones provide the best results for your flock.
Key Supplement Guidelines
Quality feed first: Always start with high-quality layer feed (16-18% protein)
Supplements are extras: They support, not replace, proper nutrition
Targeted approach: Use specific supplements to address specific needs
When Chickens Need Supplements
Essential Situations for Supplementation

- Recovery from illness: Supporting immune system and rebuilding strength
- Free-range limitations: When birds can't access diverse natural diet
Signs Your Flock May Need Supplements

- Decreased egg production: Sudden drops not related to age or season
- Lethargy: Birds less active than normal
- Pale combs and wattles: Indicating possible anemia
