It's easy with a smaller snake like a Ball but come try moving my large Blood(6 ft, 40lbs), my arboreals, or my Dum. You're going to get bit and will be in for a real rodeo. Though my Dum and Bloods are on newspaper, but they haven't what's been. I do move my smallest baby King but that's because he is so small he's hard to find and track while I offer food. It's easier to just put him in a small keeper to eat. That will stop once he grows a bit and had learned I'm good and bring food like my other young King.
I have had to remove mulch and stuff stuck in they're lips and such but it's very rare.
Also the time it would take me to feed would be insane. Going to be up to 14 snakes today so imagine moving them one by one to eat..... And where do you put six foot snakes eating large and extra large rats?
It would be a mess. Their cage is just best.
