🐦 11. Feed Birds
Crushed, sterilized eggshells are packed with calcium that helps birds lay stronger eggs.
Scatter them near feeders or in the garden.
🌸 12. Balance Soil pH
Eggshells can help reduce acidity in soil. For flowers like hydrangeas, this can even change their color — pink in neutral soil, blue in acidic!
♻️ 13. Boost Your Compost
Add crushed shells to your compost heap to enrich it with calcium and minerals.
Always crush first for faster breakdown.
