Having just hatched out some baby gargs last week, expect incubation time to be close to 100 days if you intend on incubating at room temperatures. Of course incubating at higher temperatures will speed up the process, however having babies hatch out too early just because we want them too can lead to higher mortality rates.
Mine were incubating at a steady 70 for the first 2 months and then bumped up to 72-75 for the remainder of the time due to the weather getting nicer out here. My incubation time was 99 days and the baby garg hatched successfully at 7:40 am and my fiance first saw him at 6:00am with his head poked out.
The baby took close to 2 hours to hatch out completely, but this can vary. Some babies will hatch out right away and some will take their time. It's important to let them be in the egg so they can absorb all of the yolk.
Don't bother feeding the first day as they survive off of the yolk. You can begin feeding Crested Gecko diet, or the 2 part MRPs but I personally feed Clarks Gargoyle diet as it has more protein in it and Gargoyles DO require more protein in their diet. At about 4 weeks old is when I introduce dusted crickets, and I feed them dusted crickets twice a week. It's important to have them established on both, and from my own personal experience, they absolutely flourish from having crickets in their diet.
Good luck! Hopefully they are fertile. Make sure to keep an eye on your female aswell because laying eggs does take a lot out of them and you wouldn't want her to calcium crash, and when she lays another clutch for you, you don't want those eggs to be undercalcified as this runs the risk of babies not hatching out, or babies hatching out with MBD.
Also make sure that she remains at an appropriate weight because if she loses too much weight it can be difficult for her to continue producing eggs, which can/may lead to egg binding.
Hope this helps! If you have any more questions don't hesitate to ask!
