Ahh the memories. I had show calves growing up, and a few barrows. I didn't have any help whatsoever. No one to drive the tractor to break them that way.
My method worked well, but egads took a lot of time, albeit very enjoyable time! It actually started the day I confined the calf. Getting him use to me during feeding. I would reach out and touch him, then worked up to brushing him during feeding. Then getting him used to the rope, on and off his head. Then putting the halter on.
By this time he wasn't spooked at all (probably two months has gone by). He would follow me around like a dog. I would put a leash on the halter and just work with him. Sometimes with a feed bucket. Introduced the show stick, more quality time.
Eventually (month four or five) I felt brave enough to take him out of his corral, but was smart enough to tie on a 50' rope in case I needed to head for the nearest post to stop him from bolting. Yup, had to a few times, but after that - he was broke to lead.
Come fair time, most of them were broke so well, I would let the girls up in his back and walk steer and girl around the fairgrounds!!
Mornings, before school I didn't have much time to spend with him, just a few minutes, but after evening chores - I would try to spend a hour or so most nights.
I know he is wanting a quick way to break the steer. I suppose it boils down to his kids are "too busy" doing all of the other stuff these days to enjoy spending the time to do it themselves.
Don't think I am criticizing, heck my kids were the same way, a million things to do - busy busy busy. Life was slower back then, and I am only 50!
Oh - I raised Simmental cross and one Red Angus.
