That was an incredibly interesting watch, I had no idea this was a thing.

Is there something special about where they're digging for it to be plagued with such a large amount of rats? It looks like it would take weeks to cover all of their land with this digging + dog method.

It's not a regular field.

That building you can see at about 30 seconds in is on skids, it is a barn/coop for chickens (or perhaps some other similarly small and light animal).

The bottom of the building is slatted to allow waste and other debris to fall through.

Because it's warm, and there's a constant sufficient supply of food it's an attractive home for rats and mice.

On some kind of regular schedule, the barn will be pulled along to a new location to allow the droppings/waste to be cleaned up, and the rats to be killed off.

My guess is that it's a field that was harvested in the past weeks. Harvesting crops makes a lot of edible material fall to the ground. I believe the "leftovers" from the harvest attracts the rats.

It looks maby like the remains of a row of haylage. Basically chopped corn, stalk and all, which is used to feed livestock. Usually you see this stuff in long white bags in the US country side, but there are multiple ways to store it. The stuff smells ferocious and self ferments. So they've probably used up the previous years haylage pile and now they are cleaning house so the rats don't totally mow down the spring planting their about to do.

I think 30 secs in shows a building on skids. It’s probably something like a chicken house that has been moved across the field. The rats are in amongst the old poop.
