I am fairly new to all this (within a couple years now), but since I have started owning ducks, I have had: mallard drake, pekin drake and now duck, Welsh harlequin drake, silver appleyard duck, khaki campbell drake, khaki/mallard mix duck, cayuga duck, and magpie duck. While I love all my ducks, I did really like my silver appleyard duck for her soft coloring and loud honking yell. Sadly I lost my Pekin drake, WH drake and KC drake last year to respiratory illness, but we currently have the Mallard drake and Mix Duck as adults and the Cayuga, Pekin and Magpie as younger ducklings. In my limited experience, you need to try some variety to get a feel of what works best for you. I know I have heard many talk about breed personality and whether they are more docile or social, but from the variety we have, it seems that it really depends on how you raise them and how much time you spend with them. While my Silver Appleyard was my favorite at the time, mostly due to being youngest and I liked how soft she was and she would let you rub her neck, I really cannot say that any breed has stuck out to me so far. My mallard and Khaki mix are not what you call social but come when called and will eat out of your hand when you have treats. My Pekin duckling is the most social currently and she will curl up in your lap or beside you and let you pet her. I wish I could add more to this, but I just enjoy them all and love learning all their quirks and love variety.
