Well, I confess I turned the electric fence on during the day when the squirrels figured out the new location of the feed. Didn't notice anything at the time, but now I see they don't go in the pen anymore. The gate to the pen is always open so the ducks can get to their feed all the time. There are lots of squirrels on the fence and trees surrounding our property, but they never seem to come in the pen anymore.
