I was a zookeeper back in the 1980's at ZooAmerica in Hershey, PA. A nearby hatching facility regularly sent frozen chicks to us for feeding the bobcats, birds of prey, owls and other predators.
We regularly found chicks with extra limbs in every batch and sometimes (but less often) the occasional chick with an extra head. However, most suggest this such events are not usually the result of a mutation, but instead the result of conjoined twins when an embryo only partially separates into what would otherwise be identical twins.
But I have never seen a chick with two extra legs and no wings.
