That's a big hit, I'm sorry. Like everyone is saying, good secure coop, electric helps. Like I figured, they will flip right over to late day if they know there is food, so locking them up at night doesn't help as much. A good practice on feed handling helps, coons / opossums can come in for the animal food, then end up eating birds. I'd say keep on trapping them, at least get the ones who know where the easy meals are. Keep some traps out even if they don't catch anything for a while. There is also a good dog, as long as he don't eat them. Some breeds just live to protect the flock. Good luck.
