Free: Contests & Raffles.
50 years ago had a neighbor who raised fighting chickens and was pretty proud of his flock. Another neighbor had a dog that killed chickens. Needless to say there was a problem. The dog owner wired a dead chicken through the dogs ear and made the dog drag it till the chicken rotted off. The dog would run and hide if he even saw a chicken. End of problem!! Probably go to jail in todays world.
