I have khaki campbells and welsh harlequins. I've raised all of them from ducklings, and they were all handled the same from the time that I aquired them. My WH are very docile. My KC on the other hand DO NOT like to be bothered. They're not mean or aggressive, but they prefer to be left to themselves. I love my KC, but they are just in general a more skittish breed. I also disagree with
@Tyson_chickens when it comes to ducks not being affectionate. This is one of my WH ducks with one of my daughters. We can do anything with this duck. She is constantly coming up to us for attention and loves to be held. When you hold her she will actually nestle her head under your neck when petted. I think in generall it just depends on the bird. The same goes with chickens. I have some that will jump up in my lap to be pet and some of the same breed that I couldn't handle
