bull

I went out to pull posts in the cow pens. I saw a calf eating mineral and then I saw the bull run over and chase the calf out of the mineral. I thought that was a little strange but went on. Then I noticed the bull was going all over. Wherever there was a calf away from the herd he chased it back. He didn't care how far either, 10 feet away and he was after it. I was pretty alert as to where he was. He wasn't looking to be mean or anything like that but he wasn't watching anything but the calf. I thought it was better to be safe than sorry. I've never before seen a bull herding anything.
