Why are you moving newborn calves and to where? How far away? We don't move our newborn calves for a couple of days at least unless the cow or calf has a problem. She needs to bond with the calf, and to move them too soon will have the cow wanting to go back to where she "knows" her calf is supposed to be, even if it is right in front of her.
Ditto to farmerjan. I tend to avoid moving newborns but had to last week due to scours. Just moved to next field. When you move calves the calves are always going to try to go back to the last place the fed from their mothers. I leave the gate open from the pasture they were in into new field for 24 hours. Mothers will go back to get their calves. Works like a charm. Don't try moving them. Let the mothers. But have to shut gate after 24 hours or will have cows everywhere.
