Eggshells are entirely compostable. However, instead of throwing them into the compost bin, why not try recycling your chicken eggshells and feed them back to your flock? They are a great source of calcium for your flock and you can’t beat the price, free.
Start by leaving the larger cracked egg shells intact and drying them completely on low heat (200 degrees F.) in your oven on a baking sheet for about 1 hour. It is important to bake them to kill off bacteria or mold that still may be present and that can harm your flock.
Once completely dried, place them on newspaper. Then use a rolling pin to crush them into smaller than a dime, bite size pieces for your chickens. Crushing them ensures that your chickens will no longer recognize them as eggs. This is important because you do not want your chickens to start eating their freshly laid eggs as a source of calcium. important to bake them to kill any bacteria or mold
No need to worry if you only eat a few eggs at a time. A great place to save those egg shells is in a metal pie tin on top of your toaster oven. Over the course of a few days, your egg shells will not only collect but dry as you use the toaster oven.
