I'm keeping my son's dragons for him and I am a little worried. Yesterday I fed them some crickets. My son told me I could increase the amount but I wonder if I over did it? One of the dragons just ate on at a time but the other one seemed to be gorging himself. His mouth was full and he was still shoving more in. Today one of them (I Assume the piggy, but not sure) has hardly moved and his colour is a bit darker than his roomie's. Has he just over eaten or should I be worried?
