I went ferreting for a couple hours and I found 10 holes in the middle of a field with fresh droppings and they were fresh holes and I let my 2 hobs run through there for a good 45 minutes with nothing.And later there was a field with short grass in because the rabbits had been eating it all and droppings everywhere, and up in some Gorse and some trees that weren’t too thick there was quite a lot of holes and droppings so I netted one set of holes that looked fresh, nothing so I netted another lot of holes but still nothing. Were there no rabbits home or are my ferrets not bolting them? Becaus
