There is no good point to tossing eggshells into the garbage. The landfill doesn’t need your valuable resources! Save those shells for your garden
We like the idea of the eggshells being “cooked” before use just in case there would be any “nasties” on the shells. In general I’m not extremely concerned about germs, bacteria or viruses… but sometimes I figure it’s better to err on the side of caution. Cooking the shells should kill all the offenders so that when we use the shells we aren’t risking illness by handling them.
Eggshells in the Garden: Store Them Well
Keep a container in the oven to store your eggshells. We started out with a glass bread pan lined with foil. Now we use an aluminum pie pan. The bread pan is better utilized for bread!
Every time you crack an egg give it a quick rinse then place it in the oven’s container. Remove the pan of shells when you bake. After baking, while the oven is off and cooling down, place the pan of eggshells back into the oven. The residual heat will be enough to kill bacteria, but not burn the shells.
Eggshells in the Garden: Grow Better Tomatoes!
Tomato plants love a little extra Calcium. Lucky for us egg shells are just that. By following the steps in this video you will have ample supply of fine Calcium powder to use in the garden.
Another use for the Calcium is for feeding right back to the chickens. They need the Calcium to continue healthy egg production. I’ve heard it said that too much Calcium can be as bad as not enough. To prevent getting too much in the diet of the chickens put the ground up shells in a separate feed container and let the chickens eat it as they need it.
For my chickens, I like to sprinkle the egg shells on cooked oatmeal with some plain yogurt added. They only get this treat a couple of times per month so I’m not worried too much about a Calcium over dose.
