After reading many helpful posts and taking a lot of advice, we put out their first set of treats for our 10 week old hens. Vanilla yogurt, apples, and cut up bananas. They just stared at it for a while, but one by one, they rolled up their feathers and dug in. End result: Loved the yogurt, pecked at the bananas, and the apples are still untouched. They enjoyed it as much as I did seeing yogurt all over their beaks! Hilarious.
