I have two young bearded dragons a male and female. My female is growing just fine but in the last few days I've noticed that my male's thinned out some. I feed them crickets and vegetables but he doesn't seem to be gaining any weight. I put vitamin dust on their crickets and their vegetables. I've even tried hand feeding him to get him to eat more but he's just not gaining weight at the moment. He's starting to worry me and I don't know what else to do short of taking him to the vet. These are my first bearded dragons and my second set of lizards so I'm really new to this, any help would be appreciated.
