Lol, bob the fox😁. Cheers ootot 👍.
Only joking mike, are you using n/v then,or lamping?, Foxes are not that difficult to trip up, even the Leary ones fall after awhile, if like ootot says, just be patient, bait a spot and wait, very quiet with minimal movement and a background behind you so you're not skylined, just collect all your kitchen scraps in a bucket(with lid) over the week, especially the Sunday chicken carcass, broken up to stop a grab and run😃,that's all assuming you're waiting with n/v,and if using your vehicle to wait, make sure you cover it in cammo, a motor parked shining in a field that's not normally there will often make a fox wary but not allways!! Don't forget about wind direction too. Don't sqeak anymore, if fox turns up on bait and dosn't stop long enough for the shot just wait it will nearly allways come back, just a waiting game😯,oh yeah and no smoking😀.
As for off the back of a truck driving round four different farms, we've seen 21 and shot 19 of them in the last couple of weeks,all with n/v so they're not that difficult to shoot, sounds like your foxes have seen it all before, are they edge of town foxes or are you out in the countryside??
