Farmers could be about to get a new technological tool to help count stock. 

Farm suppliers PGG Wrightson have teamed up with Inde Technology to use drones and AI to make the process faster and easier. 

It works by having drones fly across the paddocks and the resulting footage is run through an AI scanner to count the stock. 

PGG Wrightson CEO Stephen Guerin told Mike Hosking they've tried other technologies like infrared, but that hasn't worked so far. 

He says sometimes it can't distinguish between a tractor or a water trough to a sheep.
