Try and position it in the shade, even in the winter months, even though we think foxes will eat anything (sometimes they do) they do like fresh grub best, if the sun hits a tube and it starts to get warm you'll end up cleaning out a load of rotten meat, I put smaller quantities in the tube until they get used to coming to the area, it seems to me as if the more you let them come in for a free feed the greater the numbers that turn up through a night, but you need enough grub so they all get a taster. At this time of year I don't use the tubes, I slightly bury anything under a clod of earth, I'm using blood meat from the deer at the minute, you don't need huge quantities to keep them coming back, hide it under several clods and they turn them over for every piece, I use any gamebird carcasses in the winter, roadkill deer when the weather gets a bit harder, I find they don't get on the whole carcasses very well at this time of year, too many easy pickings for them like hen pheasants/young rabbits, etc. Rabbit paunch is a good draw, and I lay down the head and ribcage. When I'm running short of stuff I cut the breasts of a pigeon then chop the rest of the carcass in half, so one pigeon is giving you four mouthfuls, make them work for it. A good size roadkill carcass in the winter will last a few nights, even when you get a few foxes on it, it's nice when you check and you see it's been hammered in a night, tells you a few foxes are visiting in one night! I just knock in a fence stake and fix a 4' length of 6" pipe to it with a 45-degree angle at the bottom. Good luck, hope it works as well for you as it has for me!
