Our chickens have the run or our 60 or so mixed fruit tree orchard and today at about 3:00 P.M. or so something got one. I found it at 4:00 and it was still partly warm. The chickens don't roost until around 7:00, and we're in N. Central Oregon. The chicken had been opened up and some entrails pulled out but the main damage was to head and neck. The head was severed but not missing. The entire neck was eaten to the bone, but not severed nor was there any sign of tooth or bite marks. We do have both red-tailed hawks and owls here, so I think probably one or the other. Any ideas? This was a full grown Barred Rock hen, 1/4 of our total flock of 4! We don't keep a roosted with them, too noisy but haven't had problems with raptors before. Anyway, experienced thoughts welcome!
