I don't buy grit. My birds (chickens and ducks) have access to dirt in a huge run. Actually it's only dirt because the grass has been eaten. When they pick up bugs or spilled feed they also pick up grains of sand so they don't need any commercial grit at all.
For the chicks (8 weeks old now) I dig up a small patch of grass with the roots and dirt still hanging to it and they get their grit from that. They're still enclosed in an outdoor pen that's off the ground but I wanted them to get greens along with their grower pellets.
