After work / school, kids and I went back to barn. Dogs were really on edge every time the chickens made alarm calls. I policed up another carcass. Of the 20 chicks, 3 have been accounted for an penned, 6 carcasses found where 4 were headless. That means 11 chicks and their mother are not accounted for. I suspect strongly that at least some are still in the high weeds of the poultry yard.
When I encountered this headless chick on path leading to barn I assumed owl but started to waffle on that when seeing a trail of feathers. Chick also small enough for owl to pack off in flight unless dogs flushed it.
This pile of 4, including one with head on, was found in a heavily traveled pathway.
The heavily traveled pathway. Fox did this over night so something is up.
Location were something major happened. Looks almost like a deer bed.
Path used by fox carrying carcasses I did not find in poultry yard. Based on colors of feathers, more than one color type carried through.
Path I could see once fox outside fence. Dog working track that was cold. Fresh, then I could smell it. Red Fox have very strong smell.
