The rooster that got eaten was outside the enclosed fence. I have a couple that have taken to flying over the fence (6 ft.) and then back over to roost at night. This attack happened during the daytime.
I recently lost 5 to an early daytime coyote attack. One found dead but no parts missing, one found dead with the head missing only, and 3 gone, only feathers found. A neighbor saw the coyotes, and I found a single coyote track near my back door.
