It should give you some ideas about what you should and shouldn’t do. But before we can get to using them we need to prepare them properly! So let’s get this show on the road.

Fresh duck eggs

I wanted to take this opportunity to show off these gorgeous duck eggs that I got from my friend Teresa over at The Sheltered Valley – Home for wayward animals. Why am I sharing them? Well, #1 the are gorgeous and #2 they make up some of the eggshells I am preparing to use in my garden so it seemed relevant. Did I mention she has donkeys? This is Christopher and he was my favourite (just don’t tell the other donkeys).

His nose feels like velvet and he is adorable. Anyway back to eggshells! I saved mine up in a very large mason jar. See how some of them are all crushed? Yeah, don’t do that. Hindsight being 20/20 and all that sh*t. Keeping the shells as whole as possible. It makes the whole process waaaay easier!

Also, I would suggest giving them a quick rinse before popping them in the jar. This helps to remove as much of the albumen (the clear stuff that turns in to the whites when cooked) as possible. So in the spirit of full disclosure, I packed mine so tight in the mason jar that it was damn near impossible to get them out. On top of that, they were all crushed up in little pieces. I then had the bright idea (insert lots of sarcasm here) to put them in a big pot to wash them.

Again…unless you are in the position that you current have said jam packed jar of eggshells skip the washing step. Fishing out loads of eggshell pieces and then trying to get them somewhat dry was a nightmare. This is why I suggest giving the eggshells a quick rinse before popping them in the jar.

Drying eggshells in the oven

The next step is to lay them out on a lined cookie sheet. Then they can go into the oven at 200F for about 30 minutes. Essentially we are trying to kill off any of the salmonellae that may be lurking on the eggshells. Once the time is up move the eggshells to a large bowl.

At this point, you need to crush them as much as possible. Then you can either move them to a mortar and pestle or put them in your food processor. The key is to get them as small as possible. I used my NutriBullet and it worked amazing! This is important regardless of whether you are using them directly in the garden or adding them to your vermicomposting setup.

Powdered eggshells

Once they are ground into a powder you are done. You can now use them in any of these 3 ways to use eggshells in the garden.

Happy gardening!
