My house chicken used to enjoy the outdoors in the summer but this fellow (Seen here using my pond as his private cooling pool) has become a worrisome visitor. I've tried ammonia, pepper spray, and noisy pots and tin cans tied to the fence, but nothing dissuades him for long. Black bears are protected here and cannot be shot except in extreme circumstances. This fellow has yet to earn his first ear-tag as a problem bear, but I don't want my hen to be his first strike. The local jays and ravens have always been a great warning system when hawks, eagles, coyotes, or raccoons have been in the area, but this big guy they are silent around. He's walked within ten feet of me without me hearing a thing until I looked up and there he was. Does anyone have any suggestions to discourage him from enjoying my yard. I'm on the California side of North Lake Tahoe.
