I was told about this like 5 years ago, but I never see any meaning to it... Lol
I think I have a better understanding now, nothing is a waste, except we don't know their usage. I've been throwing away egg shells all this while because they mean nothing to me.
I know it's very reach in calcium like other shells, but I never know it can be accessed by plants.
I think grinding and mixing it with animal feeds would serve the same purpose too?
Thank you sir for this helpful tip
I know that chickens really like to peck the ground up shells, and it helps them! Good idea!
