I was looking out the window one day last week, and saw this little guy on a low branch of a tree right at the edge of the deck. He was about the size of a basketball.
The dogs hadn't seen it yet, and I quickly called them all into the house. Then Dane and I used a rake and a long pipe to herd him down the branch to the end until he dropped off in to the pasture (the tree hangs out over the fence). The porcupine, probably a young one, was trying to climb back up the fence into the yard and was a really quick climber so we further herded him out the pasture gate and off into the pine woods. Porcupines don't herd well and when you push them they tend to hunker down. Hopefully he will be happy out there and not try to come back in the yard.
