The ribs have been removed so you can stuff the bird and slice easily. A poussin is also called a spring chicken. It is a young, small chicken that is all white meat, even the legs and thighs. With an average weight around 1 lb., these birds are great for the grill, smoker or roasted in the oven. Our Poussin are perfect for a mid-week dinner because they are so lean and cook very quickly. When cooking, make sure to baste often to keep the meat juicy.
