Around the D.pond there is a 2 foot high rope fence around the pond. We
stapled bird netting to the top of the posts around the majority of it and
then held about a 1/4th of it down to the ground with some rocks. One
helper was telling us that she was told the ducks would still walk
underneath the netting. This would mean hopping the lower portion of the
rope, or ducking under (no pun intended). Would the ducks do this? On a
nice day people are walking through this area and I didn't think the ducks
would want to find themselves trapped under that bird netting? What do you
all think? ~ jan

I personally can't help you, but ducks are discussed in
sci.agriculture.poultry which despite the name, is frequented mostly by
hobby poultry keepers.
