I live on a farm and have about 90 chickens. I've recently lost several chickens during the overnight hours to a predator that only takes the heads. It also looks like the hens have been drained of blood. Can anyone tell me what type of critter this might be? The bodies appear in tact. Needless to say, I am now locking up the hen houses at night but I really want to catch this thing. It's also gotten two of my 90-day old ducklings. Any help will be very much appreciated! Thank you!
