Children and chickens must be always picking.

The saying compares a child's appetite with a chicken's repeated pecking. Both are pictured as wanting food in small amounts throughout the day.

It treats a child's frequent requests for a bite as unsurprising. The comparison is an observation about appetite, not a rule about when or how much a child should eat.

Use the saying as a lighthearted remark when a child asks for another small snack, or when someone notices how often a child wants a bite. It acknowledges the pattern without offering feeding advice.
