Remember an electric fence only works if you are also touching the (or "a") ground when you touch the hot wire. If the bear's up on top of the coop, as he'd almost have to be in order to get zapped by a wire 6' in the air, he is unlikely to be well enough grounded to get much of a shock. You could wire all your coop mesh to a ground pole, but what if he's mostly standing on the wooden frame? A neutral wire strung a foot or two away from the hot wire and wired to a ground rod *might* work (making it a positive-neutral fence instead of a "regular" electric fence) but honestly those fences don't really work as well as "regular" ones, especially since in this case it'd be hard to guarantee the bear touched both wires simultaneously.
I think you really SHOULDN'T use shockwire, electric twine or aluminum wire. They are so weak they can virtually be broken by human hand. One swipe from a bear, or just a bear bumping carelessly into them, and *ping* no more electric fence. (I use them to horseproof my wooden fences precisely because they're weak and a horse is unlikely to get hurt if he gets tangled in them... but therefore I know just how easy it is to break through them). Use electric rope or electrobraid, although unfortunately they cost more, or at least a relatively large-gauge (strong) steel wire, which would be cheaper.

Gee, bears can break into peoples' houses. It might be real hard to bearproof a coop. OTOH, if you could build it strong enough, you could just make sure they had enough indoor room that they could stay inside 24/7 if you had to go away for a few days.
I still think if you intercepted bears before they got near the coop, they'd be a lot less likely to get excited enough about chicken dinner to bother breaking in. Me, I'd probably try to run a fence around as large a portion of yard as I could afford and was convenient -- even just a page-wire (farm fence) fence -- then run a couple of lines of "regular" electric at maybe 3,000-4,000 volts along the outer top of the fence.
The idea would be to slow the bear down and get him to poke his head up to look/climb over the fence, whereupon he gets popped in the snoot by the electricity and thinks "ow, that hurt! Well, I don't see anything especially exciting on the other side of the snout-biting fence so I suppose I'll trundle off elsewhere". This avoids the dangers of very high voltages and low-hung wires.
You might talk to the folks at www.premier1supplies.com and see if they have any suggestions, they sell lots of really good-quality electric fence stuff and are good at advice.
Good luck,
Pat
