Coral from fish tank

[Tweeza]

Does anyone know if the coral used in the bottom of fish tanks would be okay to use as "grit" for chickens? We had a fish tank and still have the coral hanging around. Was hoping to wash , crush it up a bit and give it to the chickens.

Thanks

Don't know about grit (should work) but crushed coral is made of the same compounds as oyster shell so it could replace them I would assume.
