It's always nice to read these forums from time to time to reassure myself I'm not the only crazy person that digs worms for my ducks...
As for the op's topic, I have 4 runners and the 3 females are able to fly over a 2' fence, but they rarely try this. I would also tend to agree with the others comments about runners being nervous. Had I known this before I got them, I may have considered the WH more than I did. However, at the time I was looking for a good foraging duck and an active breed for garden pest control. Honestly, my runners almost seem too nervous for the smaller garden I have, it would be nice to have a duck that didn't run away every time you move wrong or wear something "different"
