I purchased a bag of chicken grit at Tractor Supply a couple of years
ago. It said right on the package that it was crushed granite. When
I got it home and opened the bag, it did not look at all like granite
to me, just a rather uniform grey color. I thought it looked more
like limestone, but the package did say granite. I should have
trusted my instincts.
I wedged the chicken grit into the clay, and threw a shelf full or
pots for a wood firing. They all came through the bisque just fine.
Still looked fine the next day. Went out to the studio on the third
day to find an entire shelf full of tiny shards of clay sprinkled
liberally with puffed up, fluffy white rehydrated lime.
I called the chicken grit company to inform them of the labeling
error. They said that they just package and sell the stuff, and they
didn't care at all what the supplier sent them. Great customer
service!

Hi Rimas, Lee, all...
Chicken Grit is usually crushed Oyster Shell.
Pigeon Grit is usually crushed Oyster Shell, crushed Granite, and Charcoal.
Canary, Parakeet, Finch Grit is usually crushed Quarts or other hard opaque
Rock, and
about like very find Sand...though they also will benefit form finely
crushed Oyster Shell.
Birds/Avians/Theropods masticate their food with an internal Organ known as
a Gizzard.
Grit or small Stones, are used by the Gizzard for the mastication to be mor=
e
thorough.
For Hens, sources of assimilable Calcium are needed to support the
production of Egg Shells...so their Calcium needs are
greater than those of Male Birds.
Hens store Calcium/Boron/Manganese/Phosphorus compounds, in or as their
Skeletons...so Organic or Mineralogical sources of Calcium and related
are broken down and molecularly delivered to and stored 'as' Skeleton, with
the reserves drawn on then and molecule-by-molecule, removed and directed t=
o
the Oviduct process, when producing the Shell of the Eggs.
Quite clever of them, I'd say...
In people, dairy products remove Calcium and accompanying compounds from th=
e
human Skeleton, thus costing more than they had contained in these
materials.

In these parts, you can get crushed granite grit of various sizes.
When I worked at UPS and took care of the tractors and trailers and
also delivery trucks, we used this grit for winter traction. The
Tractors have containers in front of the tandem power wheels and it is
dispensed by flipping a switch in the tractor. In the delivery
trucks, there is a 5 gal bucket bolted to the wall behind the
bulkhead. I keep a coffee can of the stuff in my car in the winter.
