To get the most from your electric fence, you do need the 3 grounding rods. I learned this the hard way with pigs last year. One will give a tingle, two a snap but 3 keeps trouble on both sides of the fence away.
For my ducks and geese, I have just run a 100' welded wire, 6' tall fence. Top will be covered with a plastic poultry fencing [looks just like regular chicken wire but a little thicker] and I am putting up the 5" stand offs for electric fencing. Since I live in the woods, I will be using a 50 mile electric fence charger and 3 ground rods.
As for moving the rods later, my son came up with a slick way to get them out easily. Take a pair of vicegrips and put them onto the rod below the fastener for the ground wire and then put a bottle jack underneath the visegrips and just jack them out of the ground. You might have to move the wire fastner a couple of times but this does save a lot of grief.
