I never shipped live animals before I but I have a feeling that they'd make you fill out all sorts of other forms and crap and special this, special that, all adding up to bucks. For a live bird, that's at least 20 dollars for that box with the priority mail, just for a large pri flat rate box, and I doubt a roo would fit in one. This is why I am thinking it is some sort of local thing only. he's advertising in facebook, probably thinking he's just hitting a local *in town* community where someone can go drop em off with a pickup truck or something.,
If you were willing to meet him halfway, another option might be, they have these postal stores all over the place, heck, even the gas stations are now acting like dropoff points, go find one half way and have it delivered there, they call you on arrival and you go and get it.
