I could sex them. I just dont want to tip them off to anything and have them change their minds. No idea on weight. The only thing that makes me nervous is they got one a year ago from a reptile show and two from a breeder. Odds are neither a breeder at a show or any other is just giving away his females. Males would not be the worst case scenario because i could unload them and get close to what i paid, but i would need to feed them. Its not a huge risk but i wanted some extra opinions. Thanks!
