Woke up this morning to my Cham looking Larger than normal. Not sure if maybes she’s nearing the time to lay eggs... I have been researching laying bins but haven’t found much info on what to make them out of or how... all I have seen are these huge garbage bins that will not fit my enclosure. I know 12x12x12 is a good size... what kind of substrate? and what are signs she’s laying. If anyone has pics of their bins it would help!!
