For some reason I just noticed you are Canadian and what's more, you live completely across the continent from me.
Technically, the black bears that are here are the exact same species that you have [COLOR=0000FF]BUT[/COLOR]...they have been raised in a totally different environment and must have had to acquire different survival skills than our bears. While our bears eat lots of fruit as well, they aren't taught to catch as much fresh meat as yours. They essentially have different dietary requirements, based upon how their moms brought them up. Our bears don't fish in rivers nor attack adult deer but will take fawns and dead carcasses.
These bears here do very well; moving and living in close proximity to homes and towns where they can scavenge, steal dog/cat/bird feed and would be ok if people would not essentially 'hand-feed' them. with most of them, if they had an encounter with a person in a chicken coop, they would be scared to death and not very likely to come back, at least not in day time. Whole 'nother ball game.
My place is surrounded by bears, and as I said, several sows den within 3 or 4 miles of my house and I have never had a bear problem. Sure, my dogs have treed a few over the years but they were glad to get out of that tree and be on their way...not coming back for any more of that, no time soon. But yours did something alien to the 'culture' of our bears, if I can use that term. Unless a bear in this part of the country has been essentially desensitized or 'tamed', in a sense.....what happened to you just wouldn't happen here or at best...one in a million shot. JMHO...as usual.
