They are fantastic-thanks for posting. Beautiful animals.
When I lived in Lyme NH there was a very well known man named Ben Killam who was and is one of the few authorized bear rehabbers and handlers in New England. He had bears he nursed back to health (orphans for ex.). at his house.
When I heard him speak about his work when I was there it was apparent to me he was the closet thing to being a "Bear-Whisperer" I had ever seen. He could get close to them to the point where some accepted him.
I guarantee you he has answers about how to best handle your bears. Contact info is in the link for Biography.
