Hi!
Everyone has a different way of breaking a calf, so you'll probably get a few different suggestions on the best way to break him. Here's what I would do if he was one of mine.
-Since he's new to your place, I would just leave him be for a probably a week and a half to two weeks. Getting settled in to a place can put a bit of stress on your calf, especially if he has been weaned recently or hauled a long way to get to your place. He has to get used to new food, new water, new surroundings, new cattle, and new people. That's alot of adjustments!
- I always start halterbreaking by putting them in a enclosed space, throwing the halter on them and getting them snubbed to the nearest sturdy post. You should tie him at neck level (not with his head up), in case he decides to flop on his side, with about a foot and a half of rope - enough so that when he learns that that rope under his chin doesn't feel so good when he pulls back, and he can come ahead and loosen it a little. If you have a sturdy helper (parents are good for this), getting one of them to tie him to the fence post the first day might be a good idea. Don't worry about trying to lead him at this point - The first thing he has to learn is the halter means stop and its better to have him tied to a post than you trying to lead him - He's big enough now that he will not be easy to hang on to, so get him to something stationary and let him take out his frustrations on the fence. To this end, I never allow them to drag a halter, and the only time the halter is on them is during their lessons. They have to learn that the halter means they are doing what you want them to do, not what they want to do. I believe letting them drag the halter teaches them that when they want, they can just head off to the hay feeder regardless of your wishes...
-When I start halterbreaking, I like to tie them up three days in a row, for about two hours each day. NEVER leave your calf unattended. Its also a good idea to have a knife in your pocket - if something goes drastically wrong and your calf goes down and is strangling, its an in-case-of-emergency to cut them loose. However, I've never had to do this - its just a precaution. During your times tying him up, take a comb and brush out and start working on him. Talk to him and let him get used to your voice. When you can brush him everywhere, including his face and legs, its time to get out the blower. Do be careful around his legs for the first couple of days, as you said he might kick, and you don't want to get hurt. Set up a radio after he's used to you as well. This will get him used to general noise. Since your show is not until April (which is similar to when my 4-H show used to be) you have the luxury of spending lots of time with him. Tie him up on weekends throughout the year and do some work on him. Get the clippers out to get him used to them and give him a wash (weather-permitting) here and there. It will make things go pretty smoothly when you have to start working with him daily.
Its great that you are getting ready to break him now - the smaller they are, the easier they are on us...and the easier they are to teach!! I hope this information helps and if you have any questions, feel free to PM me. Best of luck with your calf.
