I have had trouble with racoons getting into our dog food. We bought a body trap and have been setting it up with tuna fish in it. Every night it gets the tuna and sets the trap off but we have no racoon in the trap. I don't know how it's setting off the trap and getting out. Last night we put a real fish in there it still set off the trap but didn't get the fish. it did pull down my garbage can with the dog food in it. So far it hasn't found the chickens. I know the longer this goes on they will soon find the chickens. Any help?
