I know when I've observed quail passing through my parent's property out in the desert suburbs they are always scratching around for stuff. I would hate to think of them not being able to scratch.
Around here, people buy "quail blocks" (compressed blocks of seeds similar in size to a salt lick) and put them in their yards to attract quail along with shallow basins of
water. I remember one time a pair came by with their newish family to have a snack. All the puffballs dispersed around the water bowl and stared into it and then back at mom. Then the mom quail put one of her feet on the lip of the basin and bent over to dip her beak in the water. All the babies (about 6), except one, then put one of their feet on the lip of the basin and took a drink. The 7th baby was hopping around and peeping - usually quail do not hop. Finally he hopped right into the basin, stood in the middle and drank his fill. Later it turned out this quail had a bum leg and so instead of scurrying along, he hopped on his good leg. He was always last in line when the family traveled but dad always brought up the rear to protect him from predators. That family hung around the property for years and "Hoppity" as he was called, found a mate and had his own family. Like his father before him, he always hopped along behind the chicks to protect them from the rear. He was a good dad.
The young quail also enjoyed playing "king of the mountain" on the quail block - each trying to get on top, then stay there. They also developed artistic skills and I swear to you, one block they carved into something resembling an antique sewing machine - complete with the empty space through the middle (through which they liked to jump). Another piece of quail block
art bore a striking resemblance to Ronald Regan. That one was dragged off one night by javalinas (wild pigs).
