wow 4K for a beardie!!!
he looks healthy, but you cant sex them until they are older, you sex them the easiest way by bumps under their tail when they get to be juvies
ive used the addicted2dragons caresheet for all my little beardies and never had a problem
4k???! I saw bearded dragons in the pet store slightly bigger than that at 130$.... Seriously you are probably not that bad off getting one from a pet store. Unlike chams lots of stores carry them and have a clue on how to care for them so it shouldnt be in a crappy condition when you buy it.
i like the ones at http://www.breedingcircle.com/ in s fla they are very pretty and johnathan is a great guy.. the patterns down the back look like people removed the scales and made chains on the back very intricate patterns
