For chicks I would cut back on treats even more or even not feed them at all, as it's essential during this growth phase that they get all the nutrients they can get, which their feed provides. They're just like little kids... they'd rather have ice cream and candy than broccoli and carrots.
If you really want to give them treats still, use them in conjunction with "training" - my chicks would get one or two mealworms while I held them - that was their reward for being handled.
