Here in British Columbia, the feed&seed places carry a number of 
grades of sharp granite grit for birds. It ranges from the very fine 
stuff for canaries through to very coarse stuff for turkeys, with 
intermediate sizes for budgies and chickens. The chicken stuff comes 
in at least three different mesh sizes.

It runs about $8 (cdn) a bag of 20kg (44 lbs). (I may be
misremebering the size of the bags.) They're not very big bags
because the stuff is so heavy.

I used to use the #2 chicken grit in my potting mixes, but the stuff
has gradually gotten more and more expensive (like everything else),
so I've switched to horticultural perlite. I still use the very fine
canary grit for some special plants because granite is actually a
good source of potassium. I also use it mixed in the potting soil
for plants that I think don't enjoy an organic soil. 

Check the farm supply places in your area (if you haven't already).
