Question about grit

[gregblackburn]

My chicks are just about 3 weeks old and I let them outside every night for about an hour. They hang out in an area of our yard that is dirt/coarse sand and peck away at it most of the time they are out there. Is that enough grit for them or should I supplement with something purchased from the store?

They should be ok since they're pecking at the dirt and sand
