Any Idea on What Breed of Duck I should Breed in my backyard?

Question:I have all the tools and experience to Raise Birds I've raised about a total of about 30 birds That I raise till a good age then release them to join the Wild AKA my backyard which is isnt as bad as it sounds its a very big backyard with a creek and woods where there can go w/e they want from there. but they were all just standard mallards, but i wanted to try something different like a Rare unique maybe even weird bird that could survive through the Wisconsin Seasons. Any Ideas?
