A Texas equine rescue group is seeking donations of feed, hay, cash, and other necessities to care for 60 ponies and horses recently relinquished by their owner.

Law enforcement authorities in Lewisville, Texas, discovered the animals residing on overgrazed pastures at a 50-acre ranch last week. Their owner surrendered the animals to Hope For Horses Equine Rescue Inc. on Sunday. No charges have been filed.

The herd consists of Pony of the Americas mares, foals, yearlings, and stallions. They have body condition scores between 1 and 4 and all are in need of vaccinations and other veterinary care, said Hope for Horses President Anastasia Keyser.

“The mares, foals and yearlings are in the worst shape, but right now it looks like all the horses are going to make it,” she said
