I have a neighbor who's pasture joins mine. He has about 8-10 cows of breding age in this pasture, also he has a bull, but in another pasture. He seems to refuse to bring his bull over to service his cows, knowing mine will break through any fence to get to his cows. This has happened twice in the last 2 months. His fence is about 30 years old or more. Mostly rusted and rotten. With no effort any bull can walk through his fence. I have field fencing with a strand of barbed wire on top that is only 3 year old. Who is responsible for the fencing? Is there in claims for me in stud fees? How much responsiblity does he have in this issue? I need help fast on this matter, because I can't get my bull back.
