I have 3 RIR's and 3 Ameracuana's(1 of which is a large Roo) They are all full grown. Will a Cat really be able to take one of these down? I free range them during the day and have watched them escape from each other by simply flying away(well 30 feet or so) or going to high spots.....Car/Boat/Fencepost etc........so much for thinking chickens are only ground creatures. They have flown over my 5' garden fence when startled. I only ask because we have a few neighbor's who do have outdoor cats and I have seen them come through our 10 acres. They seem to show zero interest in the chickens and even ran from my rooster when he chased them. Any thoughts??
