DeliDel's duck legs are derived from the traditional French country duck breed, which is characterized by a slow growth rate. It is also well recognizable for its black and white colors.
Duck breeding has been awarded a very carefully regulated and supervised Label Rouge certificate. According to it, ducks must be of the traditional rural breed, they must not be fed genetically modified feed and they must not be fed antibiotics. Ducks may be fattened only by traditional outdoor rearing and feeding with south-western French maize. The certificate therefore guarantees very high quality and ethical meat production.
