Hi there, bit late for this year now,but a lot of the knack of this is to do with the height at which the Turkey is hung, tie the legs together then hang so that one person can enfold the bird in a bear hug, this ensures the wings don't flap, then another person stuns and bleeds the bird, we have found that doing it this way tends to stop any bruising whereas if the wings are grasped , this usually ends up with bruise marks. Or as someone else posted, wrap in a towel or similar, as long as the wings can't move.
