An 18 days old chick with 2 extra legs was referred and was examined after being euthanised. Necropsy revealed duplication of the ileal part of small intestine, caeca, rectum and cloaea. This chick had a normal cloaca, but the proximal parts of the relevant caeca were artistic. The extracaeca, colon and rectum were normal, but the posterior end of this rectum was attached to the atretic eloaca, close to the right side of the normal cloaca. The supernumerary limbs were rather small and showed severe malformation. Two extra legs shared with a single femur, tibia and fibula and showed a pygomelus situation. The femoral, tibial and fibular phocomelia was present in the left extra leg.
