Police announced late last week they were following some lines of inquiry into the slaughter of the five chickens, which were being reared by the students.

School principal Greg Cross was horrified by the attack, saying the students at the school took it in turn to feed and water the chickens and collect the eggs.

The attack was one of a spate of recent incidents at educational institutions in Bathurst.

Vandals caused $200,000 in damage at Kelso Public School, as well as smashing the windows of school buses at Carenne School.

Two cars were also stolen from Bathurst TAFE, one of which was later found burnt out.

Police have urged anyone with information on any of the incidents to make contact with Bathurst Police on 6332 8699 or Crime Stoppers on 1800 333 000. 

Information can be left anonymously if people wish to do so.
