I think so to, they did it where a lot of loud and big trucks drive by. When they would breed I swear there would be a bunch of babies dead on the road. We also have a big population of bobcats up in the back of my woods, they'd hunt the young and the adults killing a lot of them, (Bobcats killing the minx/fishers)I think releasing them so close to backyard flock is plain stupid. I would have a lot of nice furs if someone did that here.
