Why Calcium is Vital for Laying Hens?
Calcium is one of the most important minerals for poultry, especially laying hens. A single eggshell is made up of 94-97% calcium carbonate, and a hen needs 4-5 grams of calcium daily to maintain strong, healthy eggs. Without proper calcium intake, hens may suffer from soft or broken eggs, brittle bones, and reduced laying performance.
The Role of Calcium in Egg Production:
✅ Prevents Thin & Fragile Eggshells – Ensures strong, well-formed eggs that are resistant to breakage.
✅ Supports Hen’s Bone Health – Laying hens use calcium from their bones to form eggshells, so a steady supply is crucial.
✅ Improves Hatchability Rates – Strong eggshells protect developing embryos, leading to healthier chicks.
✅ Reduces Egg-Laying Fatigue – Calcium deficiency can lead to exhaustion and egg-laying problems like egg binding.
Top Natural Calcium Sources for Poultry
Providing a natural and well-balanced calcium source is essential for optimal egg production. Here are some of the best sources:
🐚 Oyster Shells – The best slow-release calcium supplement that hens can consume as needed.
🥚 Crushed Eggshells – A cost-effective way to recycle calcium back into the diet. Ensure eggshells are dried and crushed to prevent egg-eating habits.
🦴 Bone Meal – A powerful source of both calcium and phosphorus, promoting strong bones and eggshells.
🌿 Leafy Greens – Kale, mustard greens, collard greens, and turnip greens naturally provide calcium.
🥛 Dairy Byproducts – Small amounts of yogurt or cheese can support calcium levels, but should be fed in moderation.
🌾 Limestone Grit – A highly digestible calcium source commonly included in commercial layer feed.
How to Ensure Proper Calcium Intake?
✔ Provide Free-Choice Calcium – Offer crushed oyster shells or eggshells in a separate feeder so hens can self-regulate their intake.
✔ Balance with Phosphorus & Vitamin D3 – Calcium works best when combined with phosphorus and vitamin D3, which helps with absorption. Sunlight exposure or supplements can fulfill vitamin D3 needs.
✔ Monitor Eggshell Quality – If eggshells become thin or brittle, increase calcium intake or adjust the ratio in feed.
✔ Avoid Overfeeding Calcium – Excess calcium can cause kidney damage, especially in non-laying hens and chicks.
Common Signs of Calcium Deficiency in Chickens
❌ Soft or Shell-less Eggs – Hens lay eggs with weak, rubbery shells or no shells at all.
❌ Brittle Bones & Lameness – Calcium-deficient hens may suffer from weak legs, fractures, or difficulty standing.
❌ Decreased Egg Production – Hens may stop laying altogether due to stress and poor calcium levels.
❌ Egg-Eating Behavior – Some hens begin eating their own eggs due to calcium deficiency.
Final Thoughts: Keep Your Hens Healthy with Proper Calcium
A well-balanced diet rich in natural calcium sources ensures strong eggshells, healthy hens, and consistent egg production. Whether you use oyster shells, eggshells, or bone meal, always provide free-choice calcium and monitor your flock’s health.
