When you have backyard chickens, you are going to get eggs. When you have eggs, you are going to get eggshells. Sure, you can compost them, and that is a great idea. Most people will toss eggshells into the compost pile without another thought. However, did you know there are lots of other ways to use your eggshells around the house?
Use eggshells to clean away burnt on food from your pans. Crush the eggshells into a cloth, and use them to scrub away. This works great on cast iron or stainless steel. Not so much with the non stick.
Use them in your vermicomposting. Worms love them! Extra calcium, and they compost quickly, providing great nutrient dense compost for your garden and seedlings.
Clean your garbage disposal with them. The shells help to loosen any grease or grime caught in the disposal, while lessening the smell. Simply add 3-4 shells to the disposal, run the water, and turn on. Follow with a used lemon to further cut grease and grime.
***update- some are saying this may not be a good idea, that they have seen garbage disposals get clogged up with eggshells. So, use your best judgement and caution with this idea***
Give them to your tomatoes. Tomatoes need calcium to grow, and eggshells are a great way to add that. Simply add an eggshell half to the hole where you are going to plant the tomato plant, cover with a bit of dirt, then add the plant. As the shell composts, the tomato plant will get the nutrients it needs.
Use them to start your garden seedlings. Eggshells are great seed starters. Just wash out carefully, add dirt and the seed. When you are ready to plant your seedling, the shell goes right into the ground and will compost away, while providing calcium for your seedlings.
Use clean eggshells to make your own candles. Pour melted beeswax, add a wick, and a couple drops of essential oils and you have a perfectly usable candle!
Feed them back to your hens! Eggshells are a great source of calcium for hens. Crush up the shells a bit first before giving them back to the hens, or you can risk turning a hen into an egg eater. Our girls get most of their egg shells back, and we have not had any issues with calcium deficiency. It’s much cheaper than buying oyster shell as a supplement, too.
Add to your broth as it’s simmering. Place 2-3 egg shells in with your bone broth ingredients, to gain some extra calcium. There is no off flavor added, and is easy to do.
Make your own calcium citrate Did you know that many people are calcium deficient? It’s true. Our bodies need calcium to process proteins, and with so many of us eating lots of protein, calcium supplements are often needed.(get the recipe here).
Add to coffee...what an interesting idea! This apparently helps to clarify and settle the grounds, making for a perfect cup of joe. I think we will try this idea next time we are camping and making coffee over the campfire.
