You could reduce the first-player advantage a tiny bit by allowing Black to place the duck at the start of the game, instead of starting it off the board. Presumably Black would place it on d3 or e3. (Some people think reducing the first-player advantage would be valuable. I'd rather increase it, like in tennis).
