Yes, I believe she is. Give her a place to dig with coco fiber. I have hatched 7 so far with great variation in how long they took to hatch. The first 4 were incubated at about 83 and hatched in 47-58 days. The next 3 were in a container on a lower shelf so they were incubated a degree or 2 lower. they hatched in 64-73 days. Banded geckos, unlike leopard geckos, do not seem to be temperature sexable. I have generally gotten about 50/50 males and females. Currently, the 4 that are sexable are two M/F pairs, though I have had a run of males or females in the past.
