Jim put up a deer fence around our garden. It has a regular farm
electric fence pulser. It works wonderfully. If your ducks hit the
wire, even they will get the idea that they should mess with it. Jim
says he needs to get the deer fence in place before they know there
are plants they would like in the garden. They would have no problem
jumping over it! He teaches them about it with strips of tim foil
with peanut butter on them. The deer lick them, jump about 5 ft up
and 5 ft back! He says it does not harm them, but they remember as
intensity facilitates memory! He has shocked himself (accidentally)
so he knows what it feels like. Be sure the fence cannot get into the
water.
