im sure freighting blue tongues are not much different to beardies but this is how i used to freight my dragons, with the female being pregnant really not a good idea at all saying that nothing may happen but if she gets a really shaken up ride you know what i mean
i would ship them in a solid container full of shredded papers making sure there is adeqaute air holes and i would that contained inside another box thats full of shreaded paper to aid in a smoother ride for them
i would call AAE for the pricing
