Kat, we have bears as well. The biggest problem we ever had with one was our own fault. We were going to be gone for a few days and I put an extra feeder in for the chickens. I didn't want to crowd the coop and make it hard for the chooks to get down from the roosts, so I put it out into the run. Actually hung it from the roof in a corner where I could get at it easily. Mr (or Ms) bear ripped the
fencing and run all apart and pulled the feeder outside the run, emptied the feeder and left. The chooks were all safe, frightened to pieces, in the coop when I got home. I actually think, from the way things looked that it had happened just before I got there.
Anyway, from the experiences that I've had with bears I would say that they are much more afraid of me than I am of them. If I speak up loudly to them, firmly, they turn around and go away. The dog barking makes them run fast. They really don't seem to be as interested in the chickens as they are the feed, so I've learned to keep that locked in a very safe place. I'm not an expert, but I do think that with bears you can feel like you have the upper hand more often than not.
Margie, thank you for posting that link, Lynne Rogers is a great bear expert and I really respect his work. I've seen some of his documentaries regarding bears, and think it's wonderful that he knows how to encourage them to trust him. My feeling is that science is totally overlooking the bear when they look for that hidden link between animals and man. I could go on and on but....
