Hi, I was just reading all the great info you were given by duke11. How exciting that you'll be getting a new baby in a few days.
I wanted to mention that you should look for an active beardie, make sure he has all toes & a complete tail (unless you want to rescue him), see which one responds to you. Perhaps you could hold each one to see which is the most receptive to you. Most babies have stress marks on their bellies and chest, so will be almost impossible to find one without any. If you are interested in color, look for one with yellow or reddish coloring as it will get brighter as he gets older. Try not to pick the smallest one, should be at least 6" long because the smaller they are, the trickier it is to make sure everything is perfect for them. Oh and look at the eyes too, you don't want them to look sunken and they should be wide open.
What fluorescent UVB did you get, brand & % of output that it produces? Hopefully, it's the Repti-Sun 10.0 and with that particular bulb, your beardie should be 6 to 8" from it and it should be placed so that your beardie can get the benefit from it while in his basking area.
The digital with sensors and humidity readout sounds pretty neat. To take the temps, place a probe end so that it is touching the basking surface and the thermometer part on the cool side, with the other probes in different areas in the tank. Wait about 45 min for the temps to stop rising, the "out" reading is for the basking area and the "in" reading for the cool side. You'll want a basking temp of 105 to 110 (but no higher) for a baby and a cool side temp of 75 to 85 with 80 being ideal.
You might find out that you need a lower wattage household bulb on the cool side like a 40 or 60 watt so you should pick up another clamp lamp for it.
Did you get calcium and vitamin supplements? Most of us here use the Rep-Cal brand. With a baby, you need to dust their live food with calcium with D3 but phosphorus-free 5 days a wk, but only 1 feeding a day and with vitamins the other 2 days a wk, but only 1 feeding a day.
Good luck, keep us posted. :wink:
