I was told at the pet store to feed my bearded dragon 6 crickets twice a day. After looking through forms i've realized that thats not the case at all and am worried she may be underweight. I am going to feed as many as she wants for 15 minutes like i've read about, unless someone has something better to tell me. Also should i put calcium powder on the crickets for every feeding? I see mixed reviews, and are there any vitamins I should additionally be giving her besides the calcium on crickets and veggies? Thanks for the help and here are some pictures, I believe she's around 3 months. The weird looking stuff on her leg too is just some shedding skin btw.
