Grit or gravel in bird diet?

Some birds will eat too much grit, due to illness, boredom or nervousness, and will give themselves impacted intestines.

In the wild, birds get grit from eating foods found on the ground, and it helps to grind up tough plant stems and insect shells.

The diet your domestic bird should be getting from you is already soft enough to digest without additional help from grit or gravel.
