Electric fence, trap & shoot. Lock them in at dusk and let them out well after daylight. Your local preds now know where the easy pickings are and will return.
I did 6 ft tall 2x4 welded wire fence set in cement. (Soil is very firm here in E Tn so cement only goes 4" deep.) It has 2 ft tall chicken wire all around inside perimeter. I did a 5-mile 4 KV fence charger and installed 4 courses of hot wire, beginning at 8" and ending at 42" height. My coop is entirely inside of this and is on legs due in part to terrain. I close the two guillotine type pop doors at dusk and lock the entrance door in the off chance that 2-legged preds might come calling. No losses yet to coons or anything else. Even snakes and mice cannot breach my coop. Run is oversized at 2000 sq ft and so is not netted overhead. May suffer a loss to hawk or owl some day, but large population of crows hereabouts keeps hawk sightings to a minimum. 5 months no losses.
