Eggs & Meat: If you want ducks that combine good egg production and large meat birds of gourmet quality, we recommend Silver Appleyards and Saxonies. For high egg yields and excellent meat birds of medium size, Anconas, Harlequins and Magpies are hard to beat. Campbells, Hook Bills and Runners are lean, high-quality, medium-small meat birds when butchered in prime condition.
So depends on what you want. Muscovies are delicious and Pekins are great too.
