Egg shell fertilizer.

Do any of you lads use eggshells as fertilizer?. We get through dozens in a week with cooking for the mart etc. Eggshells appears to have a place in a fertilizer mix. I am thinking of mixing it with dried chicken manure and coffee grounds. Any thoughts?

I chuck mine into the compost bin.

Hi Sean. I used to do that. I found that they came out pretty much as they went in. I am now working on a way to grind them up to a powder.

I dry them out crush them up a bit and use them around plants the slugs like. Seems to work fairly well and costs nothing

We feed our eggshells back to the chooks after drying them out in the oven and grinding them.
