There are two ways to proceed at this point, and we'll do this one first.
When you come to the legs, bend the knees (one at a time) and continue turning the chicken inside-out to expose them. when you have exposed them, push them flat to dislocate them (Adriano picks the bird up and twists them back, one at a time, and it does take some effort). But doing so makes it easier to cut through the hip joints.
On to the next step.
