Tractors cause over 200 deaths per year while cows cause about 20... just to put it into perspective.. Nothing is absolutely safe
On another interesting note, COWS kill more people than bulls per year (slightly).. Granted there are a lot more of them too... So given a herd of 20 cows and 1 bull, your odds are probably about 50/50 on the attacker being a cow vs bull... I've seen a lot of people be FAR too unaware of their surroundings at our sale barn.. I had just unloaded a Longhorn bull and a couple steers, they were totally calm, people were avoiding that pen and walking in with a pair of Angus cows that were out to kill, and honestly, it's a wonder someone didn't get SLAMMED.. What I found staggering was that they didn't even REALIZE it.

While that may be true from a statistical standpoint, you need to put those numbers into perspective. Every farm generally has at least one tractor, and most farms have multiple tractors.
If you are born a male bovine, you have a 99% chance of being castrated shortly after birth, and one bull can sire the majority of modern day farmers entire herds.
The advice you gave about rubbing the bull... not very good. Especially to a person who is saying they have a bull showing aggression.
To the OP, you have a bull. You have an additional young bull that is hitting puberty. Your older bull is starting to establish his dominance over the herd to protect what he sees as his harem. If you are showing him any kind of affection, he will see you as one of two things: a threat to his harem, or part of his harem. Neither of those are going to be a good situation for you, or anyone else that is near. You may not like the advice you are getting, but you need to take that bull to the sale barn. It's good that you're asking for advice. None of us know everything there is to know, and the majority of us could do things differently than the way we "know" to do them.
