If you think you can kill raccoons and end the problems in your garden or chicken coop, think again. A new coon will be there next week. The solution that works for me is electric fencing. May a dog or something else will work for you. But wherever I lived, the supply of coons never ended.
Maybe some guys like shooting coons enough to use a chicken coop as bait. If you manage to get some eggs now and then, it's a bonus.
