Brushwolf,That is correct,shoot the second one in line first if possible.Its tempting to shoot the first one because he's closer but the end result may be better if you shoot the trailing one first.I don't normally like to hunt fox in breeding season but a friend of mine pursuaded me into some late season hunts.I told him to expect doubles which was the case almost everytime.And after some discussion we agreed that we would take the second one first and in most cases the male would run a short distance and stop.
