Babies at the meeting?
I live in CALGARY, and it would be illogical to go all the way to the coast to get oyster shell to give to chickens. That is why I assume we use crushed granite, as we get it a lot closer. It, however, is quite sharp. I also thought about filter sand. I have looked at it, and found it was just silica sand, but screened to get a uniform size. It is also not sharp, so I think I will get some. :D
