i don't handle my snake while he's in shed because he's already irritated and i think it's just nicer to leave him alone and let him do his thing. i make sure the humidity is up and give him something to rub on to get the shed off. i also chage out his water dish while he's in shed from something more flat and shallow to something deeper he can soak in if he so chooses.
how old is your snake? do you have a weight on him or any pix? every 4 days (from what i have read) is the kind of feeding schedual that you'd give a baby ball. i feed my BP every 7 days!
