Ok heres the winner, The buck runs into the brush from being chased, branch pokes a hole into the antler which is facing the outside of the beam, Its starts to bleed, which of course attracts flies. The flies then lay there eggs on the wound cause of course they want there offspring to feed, by the time the egg is ready to hatch, the antlers start to harden, which inturn killes the egg and your left with a hole from which the egg was trying to grow from the wound started by the branch?...................LOL WE ALL WIN............THERES THE EXPLANATION.
