The size of KFC chicken wings is primarily determined by their supplier, a choice made by KFC. This means KFC's control over wing size is indirect, relying on the product provided by their chosen suppliers.
Essentially, KFC selects from a limited number of suppliers, and the wing size is ultimately dictated by the suppliers' product offering, which is influenced by the size and breed of the chickens they raise. This is a brand choice by KFC to utilize specific supplier brands.
