Eggshells are the hard outer covering of an egg that protects the inside (egg white and yolk).
🥚 What they are
Eggshell
- Made mostly of calcium carbonate (same mineral as chalk and limestone)
- Naturally porous (has tiny holes for air exchange)
- Strong enough to protect the developing embryo inside the egg
🧪 Main features
- 🦴 Very rich in calcium
- 🪶 Thin but strong structure
- 🫧 Slightly porous (lets gases pass through)
- 🥚 Can be white or brown depending on chicken breed
💪 Common uses
🥗 1. Animal feed supplement
- Crushed eggshells are sometimes added to poultry feed for calcium
🌱 2. Gardening
- Crushed shells used as fertilizer
- Help improve soil calcium levels
- Can deter some pests like slugs
🧼 3. Cleaning
- Crushed shells act as mild abrasive for scrubbing pots (mixed with soap)
⚠️ Important safety note
- Raw eggshells may carry bacteria (like Salmonella)
- If used internally or in food supplements, they must be properly cleaned and sterilized
🧠 Simple summary
Eggshells are natural calcium-rich shells that protect eggs and can be reused for gardening, animal feed, or cleaning when properly processed.
