Well, that's just not true about pooping. You will find poop at the location you shot the deer with a high powered rifle most of the times.Yeah, we are supposed to either bury deer skulls and spines as deep as we can, or throw them away. But the idea is to get them out of the food chain.
I was told by several hunters if you shoot a deer and it immediately shits all over itself, its sick and don't even bother trying to track it down. I'm not sure if thats CWD related, or there are a number of other deer illnesses in my area like blue tongue and some other weird stuff.
Now, if it's not your normal fresh deer poop, then there might be something to that.
It's got to be something out of the ordinary for you can tie the two together
