Something wrong with my bearded dragon?

I have 2 bearded dragons exactly the same age but im worried about 1. I'm guessing their male and female because 1 is bigger than the other (They aren't old enough to sex yet) . The problem is the smaller 1 is REALLY small, the males about 3 times her size. She doesn't really eat, she will have the odd locust every now and then but not like she should.. She's not very active, just sits on her rock all day and has never got her head held high like the male. I have a heat lamp with a cut out timer and a florecent light in my vivarium so they get enough light and heat. I feed them on locusts, crickets, millworms and lettuce.


Any help would be appreciated =]|||Did you buy them at the same time or different times? You should try to get another bearded dragon that is around the same size as the one you have. It sounds like the bigger one is over powering the smaller one (taking all the food, etc.). Are you giving them calcium supplements? Do you have a UVB light on them? Are you also feeding them the right veggies? (kale, kollard and mustard greens). Try to hand feed her til you think she can go after food on her own.|||well first i need two know how old and it does not mean if one s bigger than it is male all might grow different and how old are they and make sure that the temperatures are the same and also some beardie are more active than others and im also wondering the last time she has pooped i really need more info to help u but as soon as u can u can email with details such as eating times least time pooped heat reading on both sides of the tank and also the humity of the tank and what kind of substrate u use
