The last rescue I had was 31gm (4 months old) so being sold as a healthy hatchling... seems a stretch the little one I had ate pinky mice and they seemed big but size according to weight of girth mine is doing really well but still is quite small for her age. If you can believe the breeder (???) a fecal maybe in order parasites MIGHT account for the size. I think it a long shot but in combination? who knows.
