I doubt I have direct access to many more turtle people than you do. I've met a few locally, but found them woefully disappointing in their experience, they seem to be banging their heads against the wall in the infancy of their experience. I encourage them to get online (amazing how many herpers AREN'T on the web yet). Most of the herpers I've learned from have been by finding breeders selling things, emailing them, making it clear I have no intention to buy, but am looking to learn. Most of them had long term email contact with me that I learned a lot from.
The two main things that I noticed with breeding were with easterns boxies and N.A. woods (and somewhat with spotteds on the one count).
1) indoors they for some reason slowly petered out with the reliable breeding
2) outdoors in extremely southern climates, the spotteds and woods and the MAJORITY (but not all, I suppose due to their range reaching that far south and some possibly being from there locally) of the eastern boxies not being reliable in the same way, which was attributed to lack of hibernation, and could be corrected with refridgeration.
These guys do this for money (yeah, I laugh at the idea of doing boxies for money, but I they were not their only species).
Personally, I find myself in absolute AWE of the box turtle. Their level of tune-ment to the environment really is amazing. The sense of direction they never seem to lose, their ability to sense weather, their common reactions to all kinds of weather systems and climate changes... I really feel these guys are natures druids. I think there's just something about the intricate mixing of nature they get outdoors that we are missing and unable to provide. It's true we can make a close approximation of nature outdoors, but we can't truly copy it, and I think we are missing some vital detail.
I'd love it if the detail was found, these guys would make AWESOME indoor breeding projects in beautiful planted zoo displays you could build wrapping your livingroom if we could just find that key. I'm not really able to devote the space that I can outdoors to indoor pens, though, so I'm not going to be working at it in THIS house (eventually I will build a custom house and I'll likely build in advanced herping rooms).
Hey, I feel for you and your importation troubles. If you've got the cajones you are more than welcome to stop by any time and pick up animals when I've got extra or when I get multiple hatchlings in a year. It'll be ALL YOU getting them home, I want nothing to do with that, but I certainly won't mind giving a knowledgeable and caring keeper as many of my hatchlings or unpaired animals as he'd like (right now I only have two sub-adult easterns available {male and a female I think}, but eggs are now incubating for three-toeds) I don't sell boxies, so if you are up for a southern adventure, let me know.
