I don't like to post about another site, but I think everyone that has a bear problem should read this. It is an article about black bear on The Clifornia Chickens site. This is a forum about chicken on Yahoo. The article is from Tezas A & M. This is information I believe everyone should read and then they may have a different outlook on these predators. Hope this helps someone. I have NO idea how to link the article, maybe someone else can.
