If you are seeing molts, that is good - your humidity is spot on. I never counted or tried to count the molts. My colony is thousands and thousands strong and keeping up with molts would be impossible.

They sold so well at the last show, we're branching out our colony to another bin. All I do is what I've put above - cat food, some occasional fruit and cricket gel. Leave them alone, they breed better when warm, dark and left alone. After a while, you will have so many you will be shocked.
