Nicking feed for livestock narks me! It ain't cheap!
Many many years ago, I did what I always used to do and took some sheep to dads for winter (he'd have the ewe lambs to keep friendly). I would leave him several bags of feed. One day, he phoned and asked if I had been and taken some without letting him know!
Charming! To start with to get to the sheep you have to go through 12ft steel gates and through a vehicle yard etc.
The next day, another bag of feed had disappeared. We assume that 25kg bags get heavy after a while as the remains of the bag was found top of a fence stuck right with corn eitherside. The culprits had left a trail too as it had been dry and their prints went off towards a neighbouring property!
Dad even knocked on their door and asked if "pilferers" had nabbed any of their feed for their pet sheep! Needless to say they were stunned BUT no more feed disappeared!
Dad doesn't get bags of feed off me now, he gets it neatly measured in tubs!
It's where I get MY paranoia from. We've had cctv since the 90's for lambing but even so, I'm one of those that KNOWS my shippon. I know where stuff is. If someone has been, I'll know, CCTV just proves it! We had a milkchurn nabbed and we waited patiently for the culprit to own up. It was a relative. He didn't think he'd have to ask, thought it was ok just to take.
