for some reason my little female beardie wont eat and is really dark and skinny but shes kinda been like this for a while and seems to eat only when she has to. we got another bearded dragon 2 months after we got her and even though the new one was smaller it was much more voracious and ate as much as possible so it got most of the food in the cage, but we made sure the older one ate. later though it seemed as though the younger one was picking on the other one. we figured if we gave them seperate cages it would improve the situation but it hasnt. any ideas what it is and how i can improve it?
