"You see it in the papers and think nothing of it, until it happens to you," he said.
There was no sign of any interference on the property - not even tyre marks by the loading ramp.
Now he's hoping someone passing on the busy highway during the last 10 days has seen something they can report to police- something that will help them catch the thief or thieves. He said the theft most probably happened at night.
Community Constable Keith Butters said there were no clues and no witnesses to the theft of Mr Ross's sheep. The amount stolen meant organisation, dogs, yards and trailers would have been needed.
"It's a big problem at the moment. Sheep are being flogged all around the place. There's something going on, because there's big numbers disappearing."
Carcasses are being found over banks right through the district, and especially out at the coast.
He's urging farmers to work together to put up cameras on rural roads, so that every vehicle can be noted.
He'd also like them to work in with Neighbourhood Support and to report anything suspicious to police and to the Farmers Weekly/Crimestoppers stock theft website.
