The way we have learned is by listening. I have heard so many stories on halter breaking, I could write a book. We have tried them all, and this the best that has worked for us. Tried and true for 10 yrs now without any problems. We get the calves to about 200 pounds and liking a bit of creep feed. Just making sure they are old enough to go without momma's for about 4 hours at a time. We put the calves in the barn, (out of the sun and in front of fans helps keep the coat nice too) and let mom cows go on about their grazing. It was hard the first year as the cows thought it was weaning time. Every 4 hours we let moms back in the pen and the calves nurse. They have halters on but no pulling them around, let them get used to the feel of them on their noses. After the 3rd nurse, on day one. We tug them off the teat, then release. By day two, we hold the halter till mom comes in, and have slight pressure until they start to nurse. Tug off more then day one, and by day 3, we have the calves walking to mom cows without knowing we are in control. Momma's milk does wonders in giving them something to walk for, not just another nasty human trying to pull their heads off getting them into the wash rack. By day 3, the cows know what is going on even if it is their first time, and will meet you at the barn every 4 hours. Works like a charm and saves our body from trying to out muscle a 500-600 pound calf that hates us for taking away his momma! But like us, you have to try and fail, before you figure out which works for you. Best of luck!
