Some breeds lay more eggs than other. I read once that a chicken is either built for eggs or meat. My best laying chickens (6eggs weekly) are fairly small and lean. All their energy goes to egg production. Like others have said, chickens spend all their time eating lol.

My not-so-great layers (2-3 eggs weekly) are round little chubsters. Their energy is divided between staying plump and egg production.
