Groton - A birth control program for deer wasn't effective in reducing herds, the state concluded after a three-year study. In a residential neighborhood, shotguns replaced contraceptive-filled tranquilizer guns this week to reduce the deer population. The Humane Society of the United States, which ran the study with the state, still believes contraceptives can be effective.
