Eggshell quality is crucial for successful poultry farming, whether for breeding or commercial egg production. Weak shells can lead to higher breakage rates and reduced hatchability. Here are some key factors that affect eggshell strength and how to improve them:
1. Balanced Nutrition
- Calcium & Phosphorus: Ensure layers receive a diet rich in calcium (from limestone, oyster shells) and phosphorus to support shell formation.
- Vitamin D3: Helps with calcium absorption, reducing soft-shell eggs.
- Magnesium & Zinc: Essential minerals that contribute to eggshell integrity.
2. Hydration & Environmental Factors
- Adequate Water Supply: Dehydration can lead to weaker eggshells. Provide clean and fresh water at all times.
- Temperature Control: Heat stress reduces eggshell thickness. Keep poultry houses well-ventilated and provide cooling measures.
3. Age & Genetic Influence
- Older Hens: Shell quality declines as hens age, so managing flock rotation is essential.
- Breed Selection: Some breeds naturally lay stronger-shelled eggs, so selecting the right breed for your needs is beneficial.
4. Disease Prevention & Stress Management
- Respiratory Diseases & Infections: Some diseases like Infectious Bronchitis can weaken eggshells. Proper vaccination and biosecurity measures are vital.
- Reducing Stress: Avoid loud noises, sudden lighting changes, and rough handling, as stress can impact egg production and quality.

🐔 Chickens recycle calcium from their bones at night to form eggshells while they sleep! Ensuring a proper calcium supply prevents brittle bones in layers.
