New Dragon Not Pooping?

[ElJanitorFrank]

I got my first dragon yesterday and they eat like a champ, but they haven't pooped yet. Is it normal for them to not poop due to stress? I'm not sure if I'm just not seeing the poop in the substrate, but if he is impacted what can I do to help?

All beardies have a different bowel movement schedule and I wouldn't worry just yet since you only just got him and still have time to fix the issues that I have a feeling you have to avoid impaction and other issues.

But instead of assuming I will ask the questions first.

What substrate/flooring/bedding does he have?
What sized tank does he have?
What temps is his basking spot,warm side and cool side, along with night time temps.
How are you monitoring those temps, digital probe, stick on gauge, or temp gun?

What brand of uvb does he have, arcadia, zoomed/reptisun, zilla, all living things or exo terra?
Is it a tube light, compact/coil bulb or a MVB?
If tube light is it a t8 or a t5?
If tube light is it a 5.0, 10.0, 12% or 14%?
If tube light how big is it, 22", 34", etc.
Is there anything blocking the UVB other than screen?
How many watts is the uvb bulb?

How old is he?
How much does he weigh in grams?
how big is he head to tail?
How many bugs does he get a feeding?
How many feedings does he get a day?
How many times a week do you dust with calcium?
How many times a week do you dust with Multivitmins?

Alright here goes:

He has a mixture of excavator clay and tile for substrate. The clay doesn't have a lot of loose particles on the top layer, it's pretty much dried into a solid piece.
He's in a 40 gallon breeder tank, so the floorspace is 36x18 inches I believe
His basking spot is about 100f and it goes down from there all the way to about 73 to the cool side
It stays around 73 all night as well
I'm using a temp gun

He has a zilla tube fixture, T8 with a 25 UVB bulb
It's 18"
It's just resting on top of the screen
15 watts

His heating lamp is just a run of the mill 100 watt bulb. I'm planning on getting a 125 watt bulb when I can because his basking spot is on the lower end of things.

I can only guesstimate he's around 2 months old,
I don't have a scale that's sensitive enough to weigh in grams
He's a pretty squirmy guy so I can't get a ruler up to him, but I'd say he's in the ballpark of 6"
He eats about 8-12 crickets and I've been feeding him 2 times a day minimum, 3 whem my schedule lets me
I've dusted all of his food with Rep-Cal so far.

That's the tank he's in right now

I advise replacing the Zilla 25 bulb as it's designed for tropical critters and isn't nearly powerful enough for a sun worshiping dragon. How far is the distance between the main basking area and the UVB light? That will help determine what the best fit is and how to arrange it. Usually in a 40g breeder tank a 22'' T5 is the best way to go. http://www.lightyourreptiles.com/22-t-5-ho-fixture-high-output-with-arcadia-d3-12-ho-bulb/

For basking light, that really depends on the temperatures you're measuring. Adjust the wattage (and/or height) so the main basking surface is around 100-110 with a gradient down to about 75-80 on the cool side surfaces. It seems like you're actually pretty close to this with what you have so maybe just make the basking site a little higher and you'll be all set.
