Is there something wrong!

Maybe her name should be "poophead" LoL.

Yeah that's her nickname. Well, a more vulgar version of that. Not in a mean way, though. It's just something silly to call her when I see her slinking out of the hide with poop smeared all over her little head and face. Maybe this is why she likes sleeping near the water dish... So she can quickly wash the poop off without anyone noticing

I wonder why your snakes poop on each other in the hide. My garters rarely ever poop in their hide, even the newborn to 2 week old babies don't poop in their hide. All my garters tend to poop in the area furthest from their hide, where their swimming pools are located. A few poop in their swimming pool, which makes it very convenient to clean out, just flush it down the toilet, rinse out the pool, wipe the surface and sides with paper towel, refill it, and return it to the snakes.
A few of my snakes when fed separately,have learned to save the poop until after they get done eating and then relieve themselves in the feeding container. That way they don't even have to have the poop in their main enclosure.
I would like some details of your setup to compare to what I have, to see if any factors in the way things are set up could possibly make a difference in a garter's cleanliness instinct.
Incidentally my corn snakes, cali king, black ratsnake, and red sided garters show the same cleanliness instinct as my Easterns. In contrast my ball python could care less where she goes!

Some just do... I have a cage with 4 albinos in it, occasionally they have poop streaks on them.

More common in communal cages.
