When starting my cow herds I bought a older Gert bull that a old fellow brought up from the king ranch.   The bull was about 7 or 8 so I turned him with the cows a week before I turned out the angus bulls just to give him a chance. well I ended up with about 60 out of 100 gert calves but had to move the cows away from the bull as he was so foot sore and tired that he just wanted to be left alone.  I also tried brangus bulls. Used them 1 year and sold them to a rodeo contractor.  They found a good home. :cowboy:
