If you are using substrate like aspen or something similar it can be hard to find the feces. I use paper towels so I don't have that problem, but I used carefresh (a type of bedding usually used for rodents) for a while and I had a hard time finding the feces. Especially if it's a hatchling, the feces are going to be small and therefore even harder to find.
If you ever do decide to soak your snake, make sure the water is luke warm, not hot, and also that it isn't too deep, so your snake doesn't have to swim. (I heard of someone putting a snake in a container of water for a while unattended and the snake drown because it had to constantly swim and it wore itself out.) If they can feel the bottom of the container they are more content to stay in the container, otherwise they are going to try to get out.
