Raptor action could involve more than one. Make certain birds roosting in coop / building. I leave carcass in place so I can work to ID and where needed adjust setup to exclude predator. Predator will be inclined to cleanup up first kill before making another. I check carcass in before dawn and at end of day to determine when predator feeds off it. Owls a little tougher to keep out although the respect bird and deer netting very well.
