Like previously stated it is partly how you handle them but partly their blood lines. In every breed you find cattle that are goofy. But figure out why? I used to raise and show PB chars and there are a few lines that were goofy. Good cattle other wise but the bloodines were speedy. not that there was a diffence between Pb and full french i had both. I found that anything with mexican bloodlines were goofy but the way they were raised and selected disposition was not a factor. Some Pb line were bad too but no more than any other breed. Sometimes cattle can have a problem with a person it might be scent or something you wear. One breeder i showed for had 2 sons one got along with the show cattle the other was a magnet for wrecks. He got kicked more than a soccer ball. One heifer calf i got ready for this family was said to be crazy and not show able. but i thought she had champion written all over her,i worked with her for a week and she was always alert but within that week became a pet and won a championship. But the one son still had problems with her. There are some chars i showed so quite and doggy they needed a boost to show well. Maybe the animals can feel that you are tense and fearful. I know that animals have a sixth sense for that sort of thing. I can tell you that maybe it isn't the char sire what were the cows like. A prime example - a fellow that has a neighboring pasture got his cattle mixed with mine. I sorted off my cattle into a catch pen and had no problems and the when his got milling around,spooked and ran thru a five wire fence and he has a heinz 57 herd some chars, simm ,herefords,angus , maines,limos,salers, and shorthorns. It is not the breed in the cattle that causes the problem his idea is that these cows have to take care of themselves and calve on grass and if he had to help them it will be with a lead pill. He feeds in fall and they stay back in the bushes until he's gone then they come out for feed. And he doesn't handle them much at all. So in conclusion when buying cattle see how they act when you get in the pen with them before you buy.
