im not sure i believe that. on the video, i saw a brown animal in a pen as the flames grew higher. the animal was in the corner of the outside pen and all of the sudden made a break for it. after a second or so inside the barn, the animal could be seen escaping the inferno, but it's hair (or flesh) was smoking as it ran. hopefully, somebody opened all the pens and that was the only one left.
they did say it on the broadcast, so hopefully all the animals were accounted for.
