I have seen Mark M lucas offer them for sale. Another option would be to breed your own--I know how small corals can be so this may be your best bet to get appropriately sized snakes. The only snafu that I come across here is that I am not comfortable freezing herps for later use or breaking their necks to freeze them for later use; but if you are comfortable doing so, have at it. Curious--will they take scented rodents or will they even take lizards? Both would be easier to obtain than snakes. Bravo though for wanting to feed the most natural diet possible.
