Yes. Highly diluted before use though. And when I pay better attention and toast the shells rather than burn them, and extract into apple cider vinegar, we add it to the chickens water.

That must make a difference with egg shell strength yeah? I learned about it via Korean Natural Farming, haven't seen it in years.
Cool, I'll have to try this.
I just give my cluckers crushed up egg shells. I do put apple cider vinegar in their water sometimes
Try and remove the thin skin on the inside of the shell.
