Thanks. That helps. I rehab beardies, so these issues are very familiar to me. I hope that i'm not overwhelming you, but there are some things about your setup that could be making him sick. Hopefully, he will feel better with a few changes.
If your UVB bulb is old, you need to replace it. If it is a florescent, they need to be changed about every six months because the UVB wears out. If the bulb is a compact (curved looking tubes) or a coil (like energy savers) Toss it. Those bulbs are proving to be very dangerous for reptiles.
You need to get a good UVB, because the symptoms you describe could be the beginning of metabolic bone disease. You should stick with either a Reptisun 10 florescent tube, a Reptiglo 8 Florescent tube, or a Mercury Vapor bulb. If you go with the latter, you need to keep accurate tabs on your temps as they produce heat. I use only Mercury Vapor UVB bulbs, and I don't need an extra basking bulb.
Now, Your thermometer is not good!!!!! Bearded Dragons need accurate temps in order to digest their food properly. If your friend uses a stick on therm and has healthy dragons, he is just lucky. You need to get a digital thermometer with a probe, and you need to lay the probe directly on the basking surface and wait thirty minutes before you get a reading. The basking SURFACE, not the basking end, should range between 95-110, or the baby cannot process his food properly. Then he needs a cool side of 75-80 to retreat to. If your basking END is in the 100 degree range, he is cooking and is most likely dehydrated.
please do get the sand out. It is a huge impaction risk for babies. Also, don't feed your baby any prey larger than the space between his eyes, unless it is a soft bodied worm like silkworms, or Hornworms. Do not feed mealworms.
What sized tank do you have him in? Can you post a pic?
