Thanks for your responses John and Kev ...

I've been in touch with a feed store and they have chick grit and hen grit
.... sounds like what I need is the hen grit.

Thanks again,

Alexander Fraser

There are different sized grit sold. What I buy here in New England is
called 'Growers Grit' and is larger than the other sizes - good for
bonsai soil use. (It is a supplement fed to chickens and turkeys to
aid in digestion).
