Should only put it in if she's had problems shedding before. SO see how this one goes. If she is looking a little duller and hiding alot then she will be getting ready to shed. Can take anywhere from a week to 3 weeks for the whole process (mine takes week and a half to two weeks).
Best not to distrub them too much. I try to check on mine every other day (if i havent seen her moving about). They can get a little stressed about it as they vision is impared and they feel vulnerable.
Mine shed last night and i've handled her twice in a week and a half just to check everything was ok.
