So far I like these the best..
1. Bacon smeared can of pepper spray.
2. Bacon smeared bag of Ammonia.(both posted just outside of the chicken coupe)
3. And as a last resort, a dead rogue black bear via 12 gauge slug, found and killed inside the chicken coupe after tripping an alarm bell. (or alarm method of choice, be careful if you are not an experienced hunter)
Any remaining bears should be deterred by continued usage of methods 1 and 2 before they acquire a taste for local home grown chickens or garbage.
I believe these to be realistic, reasonable measures to a very serious safety issue.
or you could distract the bear and lure it to your neighbor's house.(just kidding)
