help some shedding questions please

Ok few questions for you guys ak went blue last night checked on him today when I got off work and he is very blue last time he shed it was horrble so trying to make this one much easier on him couse he still had stuck shed on his head from the last time so first question is.
His humidity is at 76 right now is that to high and what do I need to keep it at? (Dont wana have it to high and cause him scale rot)
He ushually eats every friday if he is still shedding then should I hold off on the feeding or will it be ok to feed him?
Should we refrain from handling him?
How long will his eyes be this blue grey color?
And last question how long will he be in shed for like I said the first time he shed wiih us it was horrble so trying to make sure everything goes right for him.
Sorry if these are dumb questions just want to make sure he is ok we have fallen in love with him and want to give him a stress free or as stress free of a shed as we can thank you

Well when a snake is in shed i would say not to handle it. I wouldnt even worryabout feeding him either. We have some snakes that will eat even in shed but best not to chance it unless you have another snake that can take the rodent if he doesnt eat. Eyes are blued over means there deep into shed. Now once he starts to get ready to shed his eyes will clear up and his body will too. He wont look so ghostly anymore than within 24-48 hours he should shed. 78% is high in my opinion. We keep our snake room at about 55%-60% humidity and 90% of our snakes have full sock sheds. There will always be snakes that dont shed in one piece even if the humidity is at 100% just how some snakes are. Now on how long it takes for them to shed can differ. We have some that only takes a week and some snakes we have take 2 weeks. If he doesnt fully shed when he is ready then after he has tried soak him in warm water for an hour and that will loosen the stuck shed and be eaiser for you to get it off him. Never pull a shed off unless its ready to come off because it could kill your snake. What i would mostly be worried about is eye caps left on because that will damage his eyes. Hope this helps.
