So, it was a nice sunny relatively warm winter day, all chickens were roaming around my backyard and happy. A half hour later I went to the coop to collect eggs and noticed one (white leghorn) was in the nesting area DEAD. What's more, it looked like a scene in a horror movie: there was blood splattered on the walls and ceiling. There was a lot of blood coming from out of it's beak.. so it spit the blood up. Any thoughts on what happened??
