Pregnant cow rescued from well December 31, 2011 at 7:37 PM CST - Updated June 15 at 7:02 PM CASTRO VALLEY, CA (CNN) - Holy cow! Crews made an unusual rescue in California Thursday, pulling a pregnant cow that got stuck in a 12-foot well to safety. Rescuers had to drain the well, climb down into it and strap a harness onto the animal. After that, a crane got to work, gently lifting the cow out of the well. A veterinarian gave the cow a thumbs-up and she's reportedly back in a field grazing. A barrier has been placed around the well. Copyright 2010 CNN. All rights reserved.
