Can of tuna. You can even use just the fish water from the tuna. Or canned catfood. Really stinky canned catfood. They love stinky, meaty smells. If you do shoot it, don't do it in the barn; they can spray even in death. MAKE SURE YOU COVER THE TRAP before you move it. All that bad stuff you hear about skunk spray? Pretty much true. If you relocate it, you will need to go pretty far away or it might come right back for the chicken buffet. You won't likely be able to discourage it. If it were a fox, it likely would have eaten the whole chick in one go and not leave leftovers like muskelids do.
