My wife overcooked some brownies till they were hard. She then broke it up and put it out for the birds. Soon we had 6 coyotes sniffing at my fence. One of them braved enough to jump the fence and eat the chocolate brownies. It was fun to watch because she was so nervous. But wouldn't give up till she ate three pieces. These are urban coyotes so they eat almost anything. I use rabbit scent on my mojo but might try bacon grease after eating the bacon.
