You said..."when she does lay her eggs how should I care for them? I do not have an incubator so that is out of the question"...may I ask why an incubator is out of the question? Where do you live?
This is how it should go....
The female may dig more than one hole to start with but she should select one and dig it until she's happy with it. When she has it the way she wants it she will turn around butt down and lay the eggs...usually in the evening, fill in the hole, tamp it down and return to the branches. She should be hungry and thirsty and tired. Feed her well for a couple of days and then cut her diet down if you don't want her to produce a large clutch.
Once she has returned to the branches after laying the eggs, you can dig them up and incubate them.
To incubate the eggs I use shoebox sized tupperware like containers. I punch two very very tiny holes in the lid. I fill the container about half full of slightly moist vermiculite. To test the vermiculite for moisture, take a fist full of it....if you can only squeeze a drop or two of water out of it its right. I use the coarse vermiculite because it stays more evenly moist. I make dents in the vermiculite in rows about 1" apart in all directions and place an egg in each. (When digging the eggs up try not to turn them as you dig and as you move them).
Place the container(s) in a place where the temperature will be about 74 -76F all the time. Moisture will form on the underside of the lid and on the inside walls of each container.
