Limestone dust

Thinking of changing over my coop floor from shavings to sand. The girl at the sand place said I should use Limestone Dust as it's cheaper. Has anyone ever used that? Just wondering if that's even a "thing". TIA!
Located in S/Central PA. Calling for snow squalls tonight. UGH Winter needs to STAAAAAAAAAPPPHHHHH

I wouldn't use limestone dust because it is basically calcium carbonate and they will surely consume some. Using limestone dust may lead birds to die in a few months depending their age. If chicks or non laying birds it would be sooner than later.
Calcium needs to be controlled for its effect on kidneys and other organs.
