I walk through my cows a couple time a day during calveing, but other than that I only walk through them a couple times a week.  Before weaning i start working with them a little bit more and that really calms them down. When we wean i walk through the calves a couple time a day and help settle them in.  They will only bawl for about 1.5 days.

 Last year i weaned 150hd of my spring born calves by myself with no help and it took about the same amount of time as a friend of mine that had four guys on ATVs. And my calves didn't have near the health problems that his had at weaning.
