I even keep notes and record on how they and their weaned calves exit the squeeze chute. I want to open the door and have them walk out calmly. I put a flag by the ones that hit the head gate at 100 mph and bust out like Secretariat out of the starting gate.
That being said, you can have the calmest set of cows, be very selective in using high docility bulls with generations of proof of easy handling cattle and you still get the occasional outlier filled with piss and vinegar that knocks the dust off of every swing gate in the barn.
