If its an easy way to get food yes. If the bear is hungry, old or young then yes. We have lots and lots of bears around here both blacks and griz electric works for some people I like my pyrs but for those who dont have them I say frozen paintballs. I have families in my 4-H group that I get to use frozen paint balls (blue) first, then if it comes back the firecrackers that pop a million times. And if that dont work it then goes to the freezer.
P.s. Please be sure to keep yourself and kids safe. I know we all love our chickens but our human family is much more important when it comes to dealing with an animal such as a bear. I hope not to offend you by this statement but we just had a man in a town less that 50 miles get mauled because he tried to get a bear out of his coop himself instead of just shooting it or letting it leave on his own. Now his family is left without a husband or a father.
