In our steer barn we have a September born Charolais steer, he's only lived in and around pens so he's not use to the large pastures like we have at our facility. (1/2 acre pastures with 2-3 stalls) he's alone right now and we've had him for about a week now, he's gentle and calm when he's tied. We can rub all over him and he's not skittish, and occasionally he walks just fine on the lead, but he's getting worse. He throws his head down and bolts without warning. There's not a lot we can do once he has gotten to this point because he runs right at the nearest fence to try and throw us off so its either be crushed or let go. He's only 575 right now, there's three very gentle steers and a not so nice one, who has a tendency to kick but walks fine on a lead. The Charolais had no kick and no other issues when tied, any suggestions?
