The 2x4 is glued down with aquarium silicone, which doesn't hold very well, but it's good enough. The branch kind of makes it stay there.
Her diet sucks, because she won't eat greens. Buy an adult, I thought, skip the voracious insect eating phase! Well, it turned out that she barely picks at greens. I've seen her eat greens three times. I trick her into eating them by putting supers or silkies in there. I've also, off and on, made her pureed mango or swuash and stuck silkies in it. She gets silkies, as many as she can eat, in the afternoon. Greens, (collard, mustard, turnip) in the morning, finely ground, usually with a few superworms in it. I don't give her crickets, because I believe they may carry round worms. I've had her dewormed (she had three kinds of worms) and treated her for coccidiosis (they pretty much all have it- you just keep the levels down to a manageable number) and right now she has a sample sent off to an electron microscope to look for adenovirus, which is present in bearded dragons world-wide, and causes deaths in babies, and can be passed from mom to eggs. I just want to know if she carries it- not that she's been sick ever. I give her calcium on her silkies twice a week, and vitamins on her silkies once a week.
