I am new to the cattle business, this is my 4th year and I still have a small herd. My bull that I have had for over a year and is 3 years old suddenly started being really weird the last couple of weeks .... he will run full speed with his tail straight out to a particular spot in the creek any time I come around... he was still coming to eat and let me spray him but as soon as he was done he would run off ... now he won't even come eat I will just see him running with his tail out. There is a house being built close by? I don't know if that has agitated him or what? Worried he's got rabies or something? Is this normal?
