what do you think about running multiple bulls with a herd? I've always seperated cows into 30-40 cow herds and placed a bull with each, but it would be so much easier and I could rotate pastures better to run one herd. I would figure I would need to run 3 bulls, maybe 4 if they are younger. Will they establish a ranking and get along or will I have all my fences torn down by fighting. I know they do it on big ranches but my pastures are much smaller then theirs.
