We had a 3/4 Hereford 1/4 Charolais cow that went completely lunatic nuts bawling, snorting, and screaming and just acting completely berserk. (This was before Mad Cow disease or we would have really gotten scared). We figured her calf must be dead so rode all over the place looking. Found nothing. No carcass no calf. No calf outside the fence. No buzzards, just nothing. The cow kept coming up to the barn. My Grandfather was a little quicker on the uptake than me so we began searching the hay barn. Eventually we found where the ~300 pound calf had apparently gotten out and gotten into the hay barn. Unfortunately for her instead of peacefully grazing on the edge of the stacked roll bales she got between the rolls and whatever she did apparently was enough to bring an 800 pound roll crashing down on her flattening her in the hay barn. All we saw was the back foot sticking out, we grabbed a hay bar and rolled the rolls out of the way (probably can't do that with today's tight core rolles). Shockingly the Pinzgauer cross calf was still alive.....albeit exhausted and dehydrated. We dreanched her full of water and Coca-cola then barned her in a pen with her mother. In a couple of days we turned both loose happy and healthy.
