Just musing about Tony's cows now ...
Someone upthread wondered who'd be the first to stick the knife in about the suckler cows - Peggy and/or Tom probably.
It got me trying to remember if the dairy herd had a bull with it, or if they AI'd their cows? Even if they AI'd their cows, in all likelihood they would have hired a sweeper bull now and again to 'get' all the cows that weren't in calf that should be.
Dairy bulls are renowned for being a great deal more vicious than beef bulls and it's fair to assume that both Tony and Ed would have had experience at working with dairy bulls. It would be unfair to levy the accusation at either of them that they didn't have the expertise in dealing with Otto.
That said ... was Ed trying to move the bull on, even before the accident? Whenever we've had a sweeper bull (a beef one) with the herd, when I fetch the cows for milking, I would always round up the cows, giving the bull a very wide berth. He would just amble his way in with them without extra encouragement so to speak. If Ed was shouting at him or giving him a boot up the backside to move him on he would have been pretty riled even without bringing Henry into the equation.
I guess moving a suckler herd back to the yard for winter is a much bigger deal than bringing the dairy cows in for milking or moving them to a different field, as they're so used to the routine and the handling.
