Police have not caught the culprits from the first attack, says King, "there's not really a lot they can do."
King predicts the latest attack took place around midnight on Monday or the early hours of Tuesday morning and urges anyone who has seen anything unusual to report it to the police.
"You kind of think well what else could they do...if they wanted to they could walk around the whole farm and get into my cow shed and do God knows what."
