A molt is a possibility but it could be a while off. Rosies are notorious for going on looooong periods of fasting. Some times even longer than a year! They are a super slow growing species with an extra slow metabolism, 1 adult cricket a week will be more than enough food for her. The author of that book had a website with alot of the info on it and a whole page dedicated specifically for rosies. I'll see if I can find it and post a link for you
