Haiwen explains that the deformation was only noticed when the duck did not go swimming with the other ducks and displayed an apparent fear of the water. After examination, he then discovered it had chicken's feet.
Implications - The discovery made by Fu Haiwen must have been a shocking surprise. The hybrid animal has the head of a duck, but has a chicken's colorings from the neck down. It would be interesting to see which animal the hybrid beast would want to mate with. Their babies would sure be interesting!
