I was home all day Wednesday and went and checked on our dozen hens and fed them some oats in the afternoon. About 30 minutes later my daughters got home from school and noticed one of them laying in the yard awkwardly. I went inside the chickens large fenced in run to check only to find that the entire head had been severed and the entire neck was completely removed leaving a cleanly cut hole, similar to how you would find a chicken in a grocery store. However all of the organs including the heart and liver were intact. There were no other marks, cuts, scrapes or missing feathers on the hen. I almost immediately determined it easily could have been done with a knife but mulled over the possibilities of what kind of animal could be capeable of such and furthermore, leave the meat and organs behind and take the head and neck bone. Since I had been home all day I found this obviously disturbing. Yesterday my son whom is 7 and disabled had an appointment five hours away at a specialist clinic. We returned in the evening and I immediately went to check on the flock as I was worried. I started counting and realized one was missing but felt a sigh of relief when I saw her roosting up in the coop. Only when I got closer that I realized that her head was awkwardly twisted. As I approached her I could see that her neck had been snapped and her head was completely twisted around backwards. She was sitting in her favorite roost, on an egg. I determined at that moment that it was a person responsible. There just simply wasnt another explanation. I am horrified someone could do this... WHY they would do this. Its absolutely unthinkable. I secured the run with a padlock in hopes to deter further attacks but there has to be more I can do. Has anyone dealt with something like this? Does anyone know if there are legal actions that can be taken, should we catch the person?
