Plus, he was pretty new to you so not really sure of everything. I think he did pretty good to only be balking at the enclosure and not taking off for the hills. Get him to follow you/Rachel for a bucket... use nit to teach him to lead without pulling back. Then use just a little treat in your hand when getting him to lead... you can't make him do stuff... and she sure can't either with his size and bulk... gotta make him think it is really in his best interest to do it. He seems like a nice steer...and the weight was more than I would have thought from the picture.
When we had the two steers we were feeding out, T-Bone and Ribeye, they got out one night and I got them to follow me home about a half mile by shaking a bucket of grain in front of them.
This guys is pretty well fed, so he's not as treat motivated.
I like his top line which is "naturally looking straight" as opposed to those that have to be "curried and primped" to look as nice. Looks like he has a nice hindquarters... would like to see more pics...
