I put three feral pigeon carcases out in a valley a few yards apart, dog fox come straight in, found them all three he piled up and then proceeded to try and take them all in one lump, I was 200 yds away with the Duce, i could have been 20 ft away and he wouldn’t have taken any notice of me, others sit in the shadows and watch, sometimes straight at you even though you’ve got the wind in your favour, most of the time the visit in is after it has checked out the area, they back off have a wander around , come back and start again , they will come in but on their terms, I wouldn’t say they clock watch but they may be already there at that time just watching
