An equine welfare advocate is hoping to reunite polo ponies seized from a farm owned by Polo Pony Retirement Foundation operator Nancy Mackall in August with former owners who want them back.

Twenty equines were residing on the farm when Orange County, Va., Animal Control Officers removed 10 allegedly malnourished horses from the property in response to a neighbor’s complaint about their condition. Investigators also found 20 unburied horse carcasses on the property.

Another 10 horses were placed with Mackall family friend Gardiner Mulford.

Some of the seized horses are now residing at rescues, while others are in foster homes or adopted. Six of the 10 placed with Mulford have been given away or sold
