(A) Normal vs chondrodystrophic legs of 28-day-old turkeys. Although weights were comparable, the chondrodystrophic turkey (left) has short, thick shanks and toes compared with the unaffected turkey (right). (B) Legs of a 42-day-old turkey showing bilateral chondrodystrophy. The affected legs are short, thick, with enlarged hocks, and there is marked medial bowing of both legs, which has resulted in bilateral varus deformity.
