Another resident, Martine Leblanc, said she had been forced to stop keeping chickens. "I've put up fencing but they just break it down," she said. "They're not even looking for food elsewhere, they just stay near houses." Mr Royer-Perrault is lobbying city authorities to let hunters tackle the problem. "Boars reproduce very fast, and keeping their numbers down is going to be a long job," he said. "It's going to take more than the occasional cull."
