Goose (plural: geese) is the English name for a considerable number of birds, belonging to the family Anatidae. This family also includes swans, most of which are larger than geese, and ducks, which are smaller. Mature geese carcasses weigh 18 – 19 lbs. ( 8 – 9 kg) although young animals weighing 10 – 14 lbs ( 4 ½ to 5 ½ Kg) are more popular with housewives. The yield improves with mature animals. Free-range fresh geese tend to be more tender than those marketed frozen.
