Mudgun, I will disagree with your last post. For one, all "farm duck" breeds derive from the mallard except for the Muscovy, but the Muscovy is a wild breed native to central America and now making its way into Texas and places further north. There are also many feral populations of Muscovy ducks from captive birds going wild in certain areas. Muscovy ducks are protected by the Migratory Bird Treaty, so I would count a Muscovy duck in my 6 bird limit. On the other hand, the "farm ducks" that most people are familiar with are the types descended from mallards, your Peking and Swedish and Cayuga and Magpie and Rouen, etc, and those ducks can be shot without counting them in your limit. Still, you are looking at a long argument with a warden(or a judge) if the warden is unaware of that fact, and unless you go to a "pet" honey hole or a town park where domestic ducks are in abundance, it seems to me that the occasional tamie that shows up in the bag may as well count as one of your six, thus avoiding complications. Just my opinion.
