Ghosthunters are to be brought in by farm bosses after they found unexplained objects on new CCTV cameras.
Slough Fort Farm and Stables, in Allhallows Leisure Park, installed the equipment after several animals were attacked.
But what staff have spotted on their cameras late at night has left them spooked - so now paranormal investigators are taking a look.

Co-owner Karla Ditton said the objects are not animals, because they do not light up on the camera, and they move too fast to be birds.
She said: "We just don't know what they are. It's all just really weird and unusual."
The farm is set in the grounds of Slough Fort, which dates back to the 19th century.
The tunnels of the fort, which was designed to guard against invasion by Napoleon, were dug up and cleared last year after being filled for more than 50 years.
Animals at the farm include horses, skunks, tortoises, rabbits, ducks, goats and micro pigs.
The farm has been approached by Essex Paranormal, which wants to investigate.
Farm staff are considering staying there for the night and seeing for themselves what is going on.
Intrigued villagers have also expressed interest in visiting for a night.
