^^^^thank you^^^^lets be honest, that's starting to sound a lot like an excuse to not listen at all. Snakes in shed like to be left alone, its stressful for them and a time when their eyesight gets worse than it already is and their bodies are focused on removing the shed. If you need a detailed, cited and thoroughly researched scientific reason-it stresses them out. When in blue they have a tougher time seeing and therefore are more nervous, i would be too if all of a sudden my contact lenses were smeared with grease and a giant heat-emitted tree was grabbing for me. Secondly the snakes are producing the lymphatic fluid to separate the old skin from the new...handling would surely have an effect on this if done too much right? After blue and the fluid is reabsorbed, they have to focus on getting all of the old skin off which is a task on its own without being picked up and distracted from being able to do that.
Just don't hold your snake during shed, its going to cause more harm than good.
As a side note to the veteran call out, you can certainly expect much more cynical answers or no answers at all if you continue to be as defensive as you are. I've received quite a bit of advice from people doing this longer than i've been alive and even though sometimes the answers come back harsh in text form, i take the advice and use it. I don't get angry or butthurt over a response i took as harsh or cynical...that's just silly.
