Get ferreting permission first, ask the farmer do you want me to ring when I am going to your farm to ferret, soon he see what great job your doing bring all the rabbits to the van, get chatting with him if he aint busy, soon get to trust you and ask could you do bit lamping to get rabbits off road hedges and you won't lamp where there is livestock, always respect the land and ring whenever you go, don't do silly things lamping around the house all hours, but the trick for me is get ferreting permission first, farmer tells every other farmer about you they will be mad for you to sort there
