Observation :
Our hens completely reject store bought egg shells.
Normally, when we toss kitchen scraps to our hens, the first thing they get after are the egg shells. They fight over them. This last month, we had an egg shortage, so settled for a couple flats of store bought white eggs.
The hens refuse to eat the white shells. Now I have white egg sells littering their grazing area.
I never would have guessed that hens would be so discerning. It is kinda funny, but also creepy, what do the hens know that I don't.
Maybe the eggs have a residue on the shells, maybe they have little minerals in them???
It is not the color, as some of our fresh eggs are white.
Has any one had a similar experience?
