243 if your only weaning a small group here is what works well for me.When I' ready to wean I'll put the cows and calves in the weaning pasture for a few days( usually I wean 20 to 25 at a time)and get them familiar with the fences and water and feed bunks,then I will take out about half of the momma's and leave the rest with the calves. Then after they are settled down I'l take about half of the rest of the momma's out until there is only one or two calves that are not weaned, by then the first weaned calves are settled and keep the rest calm.It takes more time but I have less headaches.It's also good if you have cow you are culling to just leave her in with the calves until your ready to sell her,a cow in with the calves really has a calming effect on them,in my experience any way.Sold several cows lately and left the claves in the pasture and they hardly bawled with no momma to bawl back to them.
