Well I missed what he said, which is probably not a bad thing.
We have the same predators, except the panthers. We have raccoons, cougars and bears instead.....
We have a run with 1/4" hardware cloth buried under the floor which is covered with small smooth river pebbles and sand. 1/2" Hardware cloth on the sides and chicken wire on top. The fencing is also electrified. Coop and duck house have a cement floor, 1/4" hardware cloth over the venting and windows and shingled roofs. Built with 1/2" plywood. Maybe overkill, but we had a bobcat come around for a few days and she finally gave up. Bear also came by, but I don't think he was really interested, should have been hibernating anyway - silly old bear. No other issues so far and we've had the birds outside since October.
