How To Use Eggshells In Your Compost & Chook Systems

Mar 29, 2021

When you have chooks, you have lots of eggshells which can become super annoying in the compost bin or worm farm as they JUST SIT THERE FOREVER. Like I said, super annoying.

They’re also a rad source of slow release calcium which is beneficial for your compost systems, soil and chickens if you can feed it back to them in a fine enough form. Which we do.

My most recent story with Gardening Australia shows you how we do it – you can watch the whole thing below.

But in summary…

  • Collect your eggshells until you have a good stash.
  • Roast them in the oven at 180 degrees for 10 minutes. Roasting them helps them become extremely brittle – perfect for the next step….
  • Pop them in a large bowl and use a glass jar to smash them up. Think of it as a giant mortar and pestle. You can end up with a pretty fine substance after a few minutes of smashing.
  • Then you can either pop them in your compost bin, worm farm or mix it in with your chook’s food.

So quick, so simple! You’re welcome :-).

    Saw your segment on GA and realised we’ve been doing eggshells all wrong! Our chooks won’t really eat them in bigger pieces so hopefully this helps get their calcium up.

    Let’s just start out by saying: putting egg shells in your compost is okay; they are a rich source of calcium and other essential nutrients that plants need. Towing Aurora Colorado

    Thanks for this. I was looking all round the GA Fb page and website for your story but couldn’t find it anywhere but then saw you had a blog and decided to try here. I am off the cook my shells now.

Mounding Potatoes – Or Not

Mounding Potatoes – Or Not

There are many varieties of potatoes (aka spuds) but only two key categories they all fall into. Determinate and indeterminate. Determinate potatoes don’t grow very tall and only produce spuds in one layer of soil so you don’t need to mound them. They also generally mature quicker than indeterminate types, a good thing to know […]

I’m a big fan of eating weeds. But first, what even is a weed? A common description is that it’s simply a plant in the wrong place – meaning us humans don’t want it there as it may be compromising the ecological integrity of that place or crowding other plants we want to thrive. But […]
