I had one chicken about 3 months ago just vanish now last week another vanish, no feathers anywhere to be found. I have no memory of the first one as I didnt catch on that she was missing till a week or so later bad me. This last one was during daylight hours and she is a full grown EE, just vanished. Chickens do free range and I am out on land but totally fenced in. Is this hawks? I just cant see anything else snatching chickens during daylight hours?
