Ridgefield Police have received some calls from residents who are worried about young deer possibly being abandoned.  Wildlife officials say they are often left alone at this time of year and newborn fawns instinctively freeze and will lay motionless when approached.  People are being advised to leave fawns alone for at least 48 hours to determine whether the mother is returning for feedings. A truly orphaned fawn may show signs of distress by walking around aimlessly and calling out for several hours.
