I found 3 dead in the drive this afternoon, necks broken, a few feathers missing from the sides of the breast, but no broken skin or teethmarks at all. The only other thing I noticed was the area around the missing feathers was damp. At bedtime, the survivors numbered 7 less than last night. I saw some dog poo near the corner of the yard outside the fence. Our Great Pyrenees was still in the fence (the dead birds were all on the outside of the fence). I can't imagine that our dog would allow a strange dog (or any animal for that matter) to approach the house and kill our flock without her going ballistic enough to come through the fence and take matters into her own paws . I have seen her destroy a chain-link kennel just so she could get out to go to the bathroom. It is possible that she was on the other side of the house, and did not hear the incident. What would kill chickens without leaving teeth or claw marks, and leave them (well, three of the 7 missing ones were left)? Anybody got any ideas???
