The Corolla Wild Horse Fund is taking DNA samples from about 100 horses roaming the Currituck beaches and a farm in Grandy, where many retire after they can no longer live in the wild. The plan is to create a genealogy chart for each horse and breed some of the horses on the Grandy farm, said Jo Langone, chief operating officer of the fund.
