One pound (16 oz.) of eggshells result from about 500 crushed eggshells.
Eggshells contain 90% calcium, 6% magnesium, and 1% phosphorus.
Shells are collected from my personal backyard flock and will contain white, blue and brown flakes. Vacuum sealed to prevent leaks during transport. Email or text 319-350-4seven7five .
These eggshells are rinsed, crushed, dried and ground by an electric motor to ensure they are fine and lighter for ease of use and application.
Eggshells are natural and rich in calcium and magnesium. They have many uses such as:
• Calcium supplement for pets
• Calcium supplement for dogs – eggshells act as a binder to get rid of excess phosphorus which affects the dog's kidneys
• A natural way to controlling slugs and snails in the garden
• Boosting calcium in the soil for tomatoes and other garden vegetables
• Boosting calcium in potted plants – as an alternative to using commercial fertilizers
• Aquarium shrimp love eggshells
• Magnesium in eggshells boosts plant chlorophyll for photosynthesis
• A feed source high in calcium for chicks and chicken – preferred over oyster shells
