Animal Control will begin rehabilitating the animals, attempting to return them to normal weight and health. Two other horses were returned to a previous owner, who is handling their care.
Clay County officials said they have been aware of the problem since October and Biscardi was given several warnings.
Bond of $20,000 was set for Biscardi -- $2,500 per horse.
