Something is eating the leaves off of my sweet potato plants. The garden has a 2 foot high fence around it. The beets, swiss chard, tomatos, lettuce, squash are not touched at all. I see no deer tracks - the soil is soft and watered daily. Could it be Canada Geese or Ducks? They are around here but I have not seen them at the plants. The leaves are bitten off. It is not bugs, all of the leaves, I have 50 plants, are bitten off. The vines still run all over, it is just the leaves gone!

HELP!
