There have been cases of hatchlings eating one another. Just thought you should know.
The 41 quart is large enough, but you're going to need some sort of arrangement that will allow you to keep he humidity up at 80% or so in the cage while she's incubating. If not, the eggs won't do so well with her.
It's much easier just to buy a $40 hovabator and a $40 thermostat, and a bag of vermiculite. You could shell out $100 for a GOOD thermostat if you wanted the best success rate.
It's even possible to use the wafer thermostat that comes with the Hovabator, but you have to...well, hover over it. <lol> Set it up a month in advance and make sure you have it in a place with stable temps night and day, and use a min/max to be certain you have it set right. You may need to adjust it whenever the room temperature changes. It can give you white hairs, but it can work.
People use artificial incubation because you get a better hatch rate, and it's hard to keep conditions in the mom's cage right for eggs. She can try her best, but she's stuck with the environment you provide, and can only raise the temperature and humidity around the eggs a little bit.
