We did maternal this past season with my IJ female. We set her up in a tub with a dry nest box and a large water bowl. The ambient temps were set a 84-85 so she didn't have to work too hard at keeping temps up. The cage was misted 1-3 times per week, or as needed. All eggs looked great up to the day they hatched and we were happy with a 7/9 hatch. She began feeding immediately after babies hatched and looks as good as ever.
These guys hatched around memorial day weekend and are growing like weeds.
Good luck.
