new calf turning back leg

[ia girl]

I have a new heifer calf born on Tuesday that is turning her left back leg when she runs or walks.  It does not appear to be slowing her down at all or causing pain.  Should I do something for her?  Could it be from the whole birthing process?  She is purbred shorthorn sired by Jakes Pound Jazz.  was unable to weight her as she is in the stock field.
