This is what I do as a tracker in your situation:
First, I go to the place where the deer you shot was standing when the arrow or ball hit it. There will be short- 3-4" long -- scrapes on the ground where each of the deer's four feet "flinched" when it was hit.
Then I look past that site to see if I can locate hair(fur) from the deer on brush, or the ground. The color and texture tells me where the arrow exited from the body.
Now, I study those 4 scraps, looking at the tracks left for each foot. Each foot has 2 toes, and each of those toes can have "accidentals"- cuts in the nails made from rocks or stepping on human garbage made of metal. There are 8 chances of finding a unique Toe accidental that belongs to this deer only.
Second, having identified the deer's tracks by length of toes, width between the front feet, and width between the rear feet, then looked for the first step he took after the hit to determine the step intervals, I should know the age of the deer, the sex of the deer, and with that accidental, separating out the other deer that were with the deer shot is not that difficult. Sex weeds out half of the track, or more. Does have wider distances between their rear feet, and their rear feet pitch outward more than do bucks because does have a BIRTH CANAL between their hips!
Then there are right eye and left eye dominant deer, and that can be observed by watching where the rear foot steps on the track left by the front foot, on both left and right foot.
The dominant eye is used to determine direction of travel, particularly during an escape, or panic. Because a deer's eyes are on the side of its skull, it does not share our binocular vision, nor that of other predatory species. It must turn its head slightly to the non-dominant side to get clear vision ahead.
Its dominant side front foot takes just a bit of a longer stride than does the other -non-dominant- front foot( partly to maintain balance with that head turned slightly away from it). Even at a walking pace, or gait, you will see a bit of the dominant front foot track showing at the toe of the rear footprint that steps on and erases most of the rest of the front foot print.
BTW, the same dominant side change in stride also appears in human tracks, when people have their heads up and are looking forward, rather than down at their feet. You dominant side foot takes a slightly longer stride when you are looking forward, to check your balance visually with the signals the brain is getting from the 3 inner ear canals, where fluid levels tell the brain what attitude ( angle) your body is in. The brain is constantly checking balance to protect itself from injury by our foolishness.
Third. I make a tracking stick from a nearby dead branch, using a knife to cut notches in it to determine step intervals, and stride lengths for both sides of the deer. The sooner I determine eye dominance, the easier it is for me to locate its tracks when it leaves the rest of the 'pack".
I once was presented with the tracks of three does walking side by side around a small pond of water. It was JUne, and the smallest track was only about 1/2" long in the toes. Obviously a yearling born that year. The yearling kept much closer to the next sized track, a does with 1 1/2" tracks, and from the relationship of the tracks, I concluded that this was the fawn's mother. The last track was the largest, more than 2 1/4" long, and I took this to be the grandmother. Its not uncommon for young does to stay with their mothers even after they give birth to their own fawn, particularly if the mother does not have fawns of her own that season. Again, these deer were walking very close together, stopping when the oldest deer stopped, and moving with her at the same pace.
The tracks were left before first light on the morning I observed them, as it rained through the night and didn't quit until an hour before daylight. These tracks did not share the rain spatters in the bottoms as appeared in the mud around them.
I knew the weather because I awoke before daylight so that I could travel to the forest preserve where I was to teach a groups of Natural Science teachers how to find and read animal tracks, so that they could use these skills in teaching their kids in school, and arrive at the site at first light. That gave me time to "cut sign" and locate interesting tracks I could mark, and show the teachers later that morning.
No, its not easy, but its not something beyond the ability of any member of this forum to do, if they simply take the time to learn. I grant that after more than 57 years doing it, I do see things that even other trackers often miss- its always a surprise to me when that happens because I have struggled all my life to find the "Next track", just like every other tracker i know. But, I hit my own "brick walls" where nothing makes sense, and I can't find that next track, and the last track simply is not telling me something I should be seeing that tells me about the next track's location.
