We have done the wean and haul, fenceline, peel cows off, peel calves off, etc. They have all worked well for us. Sometimes the best way is to peel the cows off and corral them, and then turn the calves back into the pasture they just came from.
Ditto on the electricity, and it works great if you can booster your vaccines a couple of weeks pre-weaning. I think even if calves are shipped right off the cow, the feedlot down the road will thank you.
Keep your dogs tied up.
We keep all our calves post-weaning so it is really important to us to wean them quietly and get them off to a good start.
