They do stay very very inactive during shed time. Reptiles generally move around less during shed time due to the fact that they would be at risk if in their natural environment at this time. Why would a partically blinded animal risk exposing itself to preditors?

Also, without you watching them nonstop, how do you know that they did not move about and then return to the same resting position? I have thought that one of my ball pythons did not move for over a week(not even during shed).....the only reason that I knew the snake moved was because the substrate was shifted a bit and the entrance to the other hide was facing the opposite direction

Your snakes are normal...no worries
