I walked out to let the birds free range and so I unhook the fencer as I leave it off if they are out... Welll I came out this AM and the fence light showed it was grounded out!!!! I have an weedburner fencer not the tick tick tick type... Well on the other side of the fence ther is a dead possum tangled in the wires... seems he tried to dig under my run... NOw it wouldnt matter if he got in the birds are locked into the coop but he didnt the fence stopped em... so my fence tally is one coon a rabbit and a possum...
