Snakes tend to be jumpy and on edge when they are in shed, especially when they are in blue (Blueish eyes). Remember that they really can't see and anything moving can be very stressful and scary to them. It's like being in a room with things moving quickly around you but you can't see anything. When my babies go in to shed, I just leave them alone. Once the skin is off and they can see again, they are back to their normal happy selves The only time that I ever go in the cage when they are in shed is when I have to clean it and I have gotten tagged a few times from, normally, docile snakes because of it.
