Preditor attack. What did this?

[Nanno]

Yikes! I'm so sorry this happened! That had to be a very traumatic discovery. I'd feel positively sick to my stomach if I found one of my goats like that.

Coyotes maybe? They often eat only entrails and leave the rest. I'm not sure why the head was detached, but carrion birds would have taken the eyes. The severed head thing is just plain weird. I'm getting chupacabra vibes!
