Ya know, I've read this thread, and since everyone else has essentially said what I've been thinking for me, I wasn't going to post. But, and I apologize if someone else posted this, and I missed it . . .
Years ago, on another forum, a guy who works a lot with blackheaded pythons made an observation tying chronic dehydration to egg binding. I believe the fellow was Derek Roddy, though I don't have notes in front of me on it. I don't want to butcher his findings trying to paraphrase, but it makes perfect sense. That is definitely something to keep in mind breeding snakes that are more than likely not at their ideal level of internal hydration.
