 Here is a photo of a duckling with four legs which poped up on the most emailed photos on Yahoo. Apparently the duck was discovered in England at a duck farm. The two extra feet don't seem to be as correctly formed as the normal two feet of the duck. Hard to tell if the extra legs are usable or not as well. Makes you wonder what they feed ducks in England and are they down river from a nuclear power plant to get their extra mutant on.
