Electric Fencing

[RidgeRoad]

Hi!
We have a run of 30'x20' and need to wire electric to protect from predators. Most everything I have found is for wiring fencing around acreage. We are on 7 acres but only want to wire around the chicken coop, What are the suggested configurations, and any recommendation on the energizer would be appreciated. Again, we are only wiring around the run. We have bear in the area, weasel, etc.
Thank you!

I'm not sure but if I had bear to deal with I would fence not only the coop/run but also out further so a bear would get discouraged before he got up to the coop/run.
