Adults with cubs to feed are hunting hard my way, hunting up the hedges and woodland hoping for ground nesters, and searching open fields for leverets, they seem pretty wired at this stage of the game to me. Got a vixen to knobble on our patch, I got the dog a few nights ago.
I guess if you are not seeing them, you've done a good job, I'm sure as soon as the cubs start getting moved to a clean earth you may get some more...
