I agree, AnitaE, it will be one less concern for your first ducks. I love my Runners. They are energetic, but mine are not nervous. Very friendly. Not very cuddly most of the time, though they will nestle up to me if I bring a blanket and sit or lie down with them. Yes, I am that fastidious in cleaning their pen! Anyway, it seems to me that for the most part, the amount of time you can spend with the ducklings will affect how friendly they are. There is some natural variation - each duck has his or her own personality - I used to tell some of my ducks apart simply by their behavior, as a few of them were nearly identical early on. I have ducks that don't like me to touch them, but will stay a foot or two away from me. Zehn looks up into my face and calls in her loudest voice, ah AH AH AH!!!!! and used to trot right behind me till I turned around to look at her, then ran a few feet away and turned back and called to me. Zwei and Elf come up to me for pets sometimes. Vier fusses at me, but if I touch her, she wiggles her tail and flaps her wings happily. That is Zehn calling after me - when they were younger, they hated me being out of their sight.
