So far I've not had any attempt to climb or fly.
and my chams love to eat them!
I dont let the roaches free-roam though - too fast, too likely to get out. So I either put in a feeding cup or remove the roaches head (without their heads, they dont seem to run so far! but they stay alive and moving more than long enough to get eaten!)

I use no substrate. Yes they have obvious ootha egg cases.

Sandra,

Why do you remove their heads? Is it just so they won't get loose? How big are these guys?

IDK that I could handle ripping off the head
They are much smaller than dubia, the adults are about the size of a 1/2inch cricket, but maybe not quite as meaty.....
We actually found this crazy gecko in our turk bin today having a hay day!

I remove the heads when I'm not going to be sticking around to ensure the roaches get eaten. That way I know that the roach , if not eaten, will die within two weeks (from starvation). I know it seems mean. But Im so paranoid about roaches getting loose in the house that I feel it necessary. Its neat and creepy that the roaches seem to handle being headless quite well.
The Turkish are about 3cm (an inch) full grown. A perfect size. My hissers get much much bigger.
