What type of UV bulb is this as well as the model. In our hobby not all UV bulbs are created equal. Beardies as a desert creature need higher more perfected UV levels so the bulb is very important. Please let us know what kind you have.
Are you using a Thermometer/Hygrometer like the one from walmart, the one without the probes? You need to have something that will measure the exact center of your basking site. The Therm/Hygo unit i think you have is a good unit but only for overall temps not for pinpointed temps. You basking site should be at around 105-110. The ambient temp of the tank should be around 90 and the cool side of the tank (side farthest from your basking site) should be around 80. You can get a probe thermometer at walmart for around 12-20 bux or you can order a temp gun from tempgun.com which are what i use.
you should give 30 minutes to an hour for their body to warm up prior to feeding protein. What i like to do is put a nice freshly chopped veggie salad of mustard and collard greens in right after lights turn on. This enitces them to eat their greens as they are very hungry first thing in the morning. Then about an hour or 2 later i feed the first live feeding. This gives their tummies plenty of time to warm up from their lights. Just a suggestion on that though.
