Calcium for Laying Hens: Safe Sources and Feeding Control

Why calcium balance matters

Laying hens require calcium alongside phosphorus, vitamin D and adequate energy. Weak shells can have several causes, including nutrition, heat stress, disease, bird age or inconsistent feed intake.

Assess the complete flock and ration before assuming that more calcium is the only answer.

Better decisions begin with measurable farm conditions and routines your team can maintain.

Preparing clean eggshell calcium

Households sometimes wash, dry and heat eggshells before crushing them into small particles. This reduces contamination risk and makes the material easier to handle.

Homemade material should be kept dry and separate from the balanced feed unless a poultry nutritionist advises a specific inclusion rate.

Use supplementation with professional guidance

Free-choice coarse calcium may help layers regulate intake, but requirements vary by production stage and ration.

Practical checklist

• Confirm the base feed specification
• Keep homemade material clean and dry
• Monitor shell quality over time
• Consult a veterinarian or nutritionist when problems persist
