Well, maybe.... unless it all sifts down to the bottom of the feeder.I'll let my eggshells dry out and then blend them up so that they're very fine crumbles/powder and then I put it into their feed. That way, they can't NOT eat it!
Plus egg shell is not as good a calcium supplement as oyster shell.
The OS stay in the gizzard longer.
Not true.I wouldn't give the chickens shells of their eggs they might start eating their own eggs
