Yep exactly. Captive hatched could also just mean they brought in a gravid WC female who laid eggs while they had her.
I'm looking to get a pair of the southern white lips that Dan Mulleary imports if he gets any more of them. He gets really nice WC stuff and really know his sources (he actually goes to the farms there and hand picks things). For anyone that hasn't seen his videos those pythons are INSANE. For some reason the ones that he imports from that specific locality are extremely tame and while shy, they never bite. I would love to get a pair of those as they are super easy to work with and look awesome. First white-lips I've seen that are not even the slightest bit defensive, not even in the cage.
