Hi!
I want to chime in - my Runners are anything but skittish, in spite of the breed's reputation. I think some of it may be genetic, but much may be that I raised them with lots of TLC and spent quite a bit of time with them.
At three weeks, they went through the stage where overnight I became, in their eyes, a potential axe-murderer. That was a rough several weeks of learning how to keep them more calm. BYC Duck people really helped me!
And once they got through that phase, they became and still are very friendly, calm, energetic, personable critters. A few will let me pet them sometimes, no one likes being picked up, all of them will literally walk on me if I have treats.
We have also adopted some rescues. Our Khaki-Rouen mix is very very sweet and friendly. Our Black East Indies is friendly but a wee bit more shy. One of our Buffs is very friendly and even lets me pick her up when necessary without much fuss at all. Three of our Buffs apparently were not raised around people, and are relaxed until we get closer than three feet away, then they seem a little nervous. Our white Mallard is very friendly, will get right up next to me, but if I reach to pet her, she skirts away and wags her tail.
