I have 3 adults now. I started out with a 6 week old 2 years ago, and then I saw 2 beardies together in a pet store in Oct, bought both, and separated them, 1 male and 1 female, both were starving, female worse, thought I would lose her, dealing with eggs and being skinny has been hard, then being in a 200 square foot apartment is hard, looking to move to bigger place in a couple months. My big girl has bee sleeping so dealing with 2 for now, but it will be better and more room once I move.
