That's interesting and useful information.
Not sure how that would fit into US legislation exactly. As an EU Annex B species being moved within the EU for noncommercial purposes no EU permits are needed (source
). US law doesn't distinguish between commercial and non-commercial transport, though, and of course a CITES permit would be needed for export from the EU. I've heard of cases in which USFWS retains ownership of confiscated animals while they're in the care of zoos as a legal workaround; something like this would have to be in place on the US end for this to be strictly legal. US law prohibits even transportation of such species regardless of who owns them, so this would be a challenging situation.
At any rate, this sounds like a great way to structure the program. Best of luck to you in breeding them.
