Steal a road cone from the highway. Nail two corners to a stump point of cone down the side of the stump. Cut off about 2 inches off the top of the cone. Catch chicken and put in the cone head first. Cut the head off with a good knife. I think you cut the head off the chicken to kill it and to drain off the blood from the meat. Cone keeps em from flopping all over. Reduce blood spatter reduce insects. Just a suggestion. Good luck with the gun!
