How to Recycle Eggshells for your Homestead

Recycling eggshells is a wonderful way to benefit your homestead.

We collect eggs from the coop every single day. When we cook or bake the eggs we save the egg shells. Say what? That’s right. We save the egg shells. Did you know eggs are pure calcium?

Calcium is used for a couple of things on our homestead. The number one thing being our chickens. Chickens need a certain amount in order to make eggs. When it comes to meeting your bird’s calcium needs you have two options.

Oyster shells are a great form of calcium. We place a bowl inside the coop full of oyster shells for our girls. Funny thing about nature is that these birds seem to know exactly how much they need, so when they need it they eat it. When they don’t, they don’t.

Another option is to feed their eggshells back to them!

We first bake our leftover eggshells in the oven at 350 for 5 minutes. Not all people do this, but we feel better about killing any lingering bacteria. We use the same old cookie sheet because the eggshells can burn and stain the sheet.

Once your eggshells come out of the oven, dump them into your food processor. We use a plastic chopping blade to keep our metal one from dulling. Put the lid on and let her rip! It gets pretty loud, so if you have sensitive ears prepare yourself.

As the food processor does it’s job your eggshells will turn to powder!

Place them in a mason jar and store in a cool, dark place.

If you choose to give them to your chickens, place them in a bowl in the coop for your birds. Crushing them gives your birds the calcium they need and keeps them from becoming egg-eaters.

Because eggshells are pure calcium they are great for the garden as well!

I place a little bit with each seed when I plant. The added bit of calcium seemed to help my seeds sprout strong. I also sprinkle my new calcium powder into my composts. Over time my garden thanks me for it as it puts calcium back into the soil and my plants take it from the soil.

If you aren’t going to use it right away place it in a mason jar and store it in a cool dry place. I often wait until I have a quart of eggshell calcium before using it.

Do you recycle eggshells for your coop or garden? What method do you use?
