Chickens can be purchased whole, with weights that range from 3 to 10 pounds (1,350 to 4,540g); cut in parts such as breasts, thighs, legs, and wings; and even as ground meat. Some chicken parts are available boneless and skinless. Chicken is usually sold fresh, but in some supermarkets it has been frozen and thawed.

Cornish game hens (also called Rock Cornish hens) are tender, young hens that are specially bred to be smaller-boned and meatier; they have a more delicate flavour. Broiler-fryers are young (about 45 days old), tender birds. Roasters are older, about 10 weeks old. Capons are large (8 to 10 pounds or 3,600 to 4,500g) castrated male chickens that have been kept confined so their meat is tender. Fowl or stewing hens are older, laying hens, and give excellent flavour to soup or broth.
