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.

There is nothing noble in being superior to your fellow man; true nobility is being superior to your former self. -Ernest Hemingway
The man who makes no mistakes does not usually make anything.-- Edward John Phelps
