I guess eastern bears have more manners than my western black bears. They look at my coops and run as if there is a big sign on it saying, "Meat Market".
Before I installed electric hot wire, bears would be a constant problem, drawn in by the chickens. When bears sight the live chickens, I may as well not even exist, their focus is so determined. Even banging two pots together and screaming at them gets no reaction, as intent on the chickens they are. One time I even went up to the bear and dropped a big rock on its back to get its attention. Not recommended. Luckily, I didn't get eaten.
The hot wire is ineffective against the thick insulation of a bear's hide, but the secret is to mount the hot wires against a solid surface, held in place with the proper insulators. This forces the bear to "contemplate the wire" rather than evading it by jumping through the strands as when you have it as a free-standing fence.
If the bear has to scale a fence, instead of jumping over or through the strands, then you can be sure it will make contact with the hot wire as it investigates and plans how to get past the barrier. Peanut butter dabbed at intervals on the fence assures the bear will taste or smell the hot wire and get a painful shock. This will almost completely guarantee that the bear will not return.
Just because you have never experienced a bear showing interest in your chickens does not guarantee it never will happen. It's not as if they signed some kind of agreement to leave your chickens alone.
