There are lots of ducks on Chickamauga that are local born and bred.... you see them all summer. They don't migrate and they hybridize with various domestic ducks that live on the lake and end up with a wide variety of shapes and colors.
We have always called them "boat dock ducks," although they do maintain somewhat "wild" behavior patterns.
When hunting our philosophy has always been, "If they fly, they die." emoBigsmile
