I used to do it a lot Rob though it is dependant on the type of warrens your ferreting.........it can be action packed in the right areas.
Yeah, the farm I go on had a lot of warrens actually in the hedgerows themselves, netting them was a ball ache, took forever and resulted in plently of tangles, should be easier with the dog on those warrens because I can cover a fair few warrens and any bolters are running into fields with no cover around. The other land I ferret has some exits in the open and some near cover so I'll net the ones near cover and leave the others open. Really looking
