Maybe I'm unusual but I only take enough for the freezer/fridge 2-6 rabbits a time once or twice a week is quite enough to keep me going; chuck a few shot pigeons in there and my food bill with the veg garden and chickens is pretty much nil... Does anyone else "subsistence hunt"?
When I get permissions; (of which I have a few) I usually explain that this is what I do; and whilst some farmers/owners explain they'd rather have a 'total war' on pest species, but a lot, nod, smile wryly and say "like a 'fairy tale' old poacher, but done legal?" And let me crack on...
