I don't purposely feed any snakes in shed. Sometimes by accident when they've been hiding & I didn't realize until offered & they've grabbed it.
If I know a snake is in shed, I avoid feeding: some take it, some don't; most shed O.K. anyway, but some DON'T...because both digestion & shedding use up more
water in the snake's body to accomplish, and I've seen one of 2 things happen (or both) IF the snake for any reason is under-hydrated: they may barf up the rodent
after accepting it (so then it's trash) and/or they have trouble shedding because their body's hydration was insufficient to do both at the same time, so the shed gets
stuck & comes off in a million pieces. When sheds get stuck, you also have to worry about eye-caps getting stuck...just saying. So to me, this scene is best avoided.
Just remember that snakes are "designed" to fast, and in the wild they do NOT eat when in shed.They lay low because poor vision (& other senses dulled) puts
them at risk.
