Farmers bring to the Savoie markets some of the most succulent free-range birds as can ever be found; their only disadvantage is the chore of removing the pinfeathers. Even properly prepared, these birds can be a bit tough, since they have good muscles and are extremely well exercised. The toughness problem can be solved by letting the birds rest in the refrigerator for 2 to 3 days after purchasing to allow proper relaxation of the meat. In France, where birds are always half dressed, this does not present a problem; the upper respiratory organs keep the air from penetrating into the cavity, which prevents the development of bacteria. In the United States, however, the cavity is completely cleaned before the bird comes to market.
