Albino boa in shed

Hello all just wondering if anybody knows any for sure signs as to when my albino boa is shedding. i noticed her eyes weren't piercing red and very dull and she has been very hissy. If anybody has a picture of an albino in pre shed please share thanks. i just got her a week ago. i know she usually never hisses so something must be up

She will probably shed in a week! Their eyes go cloudy for a few days, it will clear up in another couple days, and then they will shed. During this cloudy stage, their vision is a bit impaired, so some snakes become a little defensive and hissy.
