if i had permission that had rabbits in rock piles or similar i'd do the same as ditch, i always feed my ferts the night before the mornings ferreting, they all kill and move on, never get a lye up, if i choose to dig i will, as regards them getting stuck, i know if they are stuck, so given time i would do it just the same if i had my terrier to ground, get some tools a few lads and a big flask,
permission is getting harder to gain, so leaving it for some wouldnt be an option!
ps the summers over now so stop bitching!
