So, I was talking with my cousin about the differences between my two ducks. The Khaki is very bright and smart with great survival instincts. Yet the mutt has always acted like she was a little slow. Then my cousin who is into horses mentioned that horses with blue eyes often have sight problems and when they get older typically go blind quickly and suggested that this might be the problem with my mutt duck. I have no idea if what she said is true, but my mutt does have blue eyes and sight problems could be the answer to a lot fo the dumb things that she does. Does anyone know if blue-eyed ducks are more prone to being visually impaired?
