Fawns give off no sent. They will not move unless you step on them or look directly at them. Fawns do have instincts for danger, but learn what animals are dangerous to them as they watch their mothers. At this time of the year you might have one run right up to you. The fawn thinks you are it's mom and meal time is at hand. It is best for all concerned to scare it away by yelling and waving your arms. Fear of man is beneficial come November 15, hunting season. Do not follow the fawn as you may drive them to far from their mother, but move away and always keep fishing.
Wolves, bears, coyotes and even foxes will prey on fawns. The fawn's best chance is to remain still, not move...one square foot is all it needs for about 2 weeks. Remember, the fawn isn't lost or abandoned...the doe is near by with her sent as a decoy...similar to a bird's " Broken Wing " technique.
