People will jump me for this, but we all do what we do. There is no way that calf is going to slaughter anyway. Even if it was, it wouldn't get there in 3 days. If you don't have anything that will hold it, just leave it on the trailer. You can hay and water it there. I'm thinking if you can get 8 feet from it, the thing can be caught without all the hupla anyway.
Be a good guess, you'd better catch it the first time you throw a rope. If it's very gamey at all, it won't be hanging around for a second shot. I'd also suggest you rope it's back leg. If it all goes south, you want won't have a wild calf running loose with a neck rope on. Possibly a neck rope with a fence post tied to it to drag
it will eventually kick out of a leg being roped.
We all work within the parameters of what we have to do, and what we've got to work with. If this is the way you guys do things, I'm all for it. Especially if it's worked before, but it's not as hard as many people think it is to kill a calf necked to something. Especially when you start dragging it. You can neck a cow with a horse, and take it to town and back if that's what you want to do. Give and release, drive instead of pull. I'm afraid your going to kill it your way.
I'm normally really good at not giving my full blown opinion, but if you don't have very many head, you don't want lose one this way.
