The feathers on the wings will move-the wings themselves should stay in place. Here are some pix to illustrate “shape.” Wings maintain a “w” type shape and the neck am “s” shape. Notice the neck is not a tube, but a series of tubes that form ovals or a figure 8 or a snowman type shape. Also the wing hanging from a wire to assist skinning. I don’t use this for duck size birds but I like it for big, heavy birds.
