Chicken sizes are commonly described by the bird’s age, weight, intended use and market specification. Names such as poussin, broiler, fryer, roaster and stewing hen are used in different countries, but exact weight ranges are not universal and vary by supplier and region. For professional purchasing, the declared weight and product specification are more reliable than the market name alone.
Bird size affects cooking time, portion yield, presentation and menu cost. Age and production method also influence tenderness, fat cover and flavour. A larger bird is not automatically a roaster, and a small bird is not necessarily a poussin unless it meets the supplier’s product description.
Specify the desired weight range, whole or portioned format, fresh or frozen status, bone-in or boneless presentation and production standard. Record the average raw weight and cooked yield to calculate portions and food cost. When ordering whole birds, confirm whether giblets, neck and other parts are included.
Example: select a consistent weight range for individual roast chickens so cooking times, plate presentation and portion costs remain predictable.
Chef’s tip: Use internal temperature and the applicable food-safety process rather than relying on bird weight alone to determine doneness. Larger birds may require a different roasting plan, but every portion must meet the required safe cooking standard.
Key distinction: Market names describe broad product types; the supplier’s weight, age and fabrication specification should determine the actual purchasing and cooking plan.
