We had a group of about 7-10 calves on one group of cows that were very high strung... cows would come right in the catch pens, came running to buckets with some grain in the troughs... but this group of calves were all very skittish. I even looked and there were 3 different bulls that were sires of these calves, too... No earthly reason for it.... most times we do not do anything but give a little feed and just check them over.... but occasionally have some idiots.
Got 2 heifers and 3 steers in the weaned ones now that are just "stupid idiots"....
