My girls are nearly 2 weeks old. After taking the advice of some of the 'elders' here, I gave them a hunk of sod to play with and eat. After ingesting a good deal of dirt (a/k/a/ 'grit'), I diced up a bit of cantaloupe and sprinkled some chick crumbles on top. Looked like peach cobbler! Well, as I'm typing this, they're chirping away happily, eating up their treat for the day.
