Many kings & corns are sold as hatchlings, & fyi, depending on the seller, many may not have been fed. While they "usually eat better than BPs", ALL snakes should be allowed time to settle in. I did assume we "could" be talking about hatchlings (which is why I mentioned they're tiny). I'm glad you didn't mean hatchlings, but it wasn't clear, & we have to remember that many people may read these posts & may conclude the wrong things if we don't specify. And I would still say that handling any new snake before it's had time to "settle in" (be feeding without difficulty) is treating it like a toy. It's not prioritizing the snake's well-being, which is what all good keepers do.
Anyway, this thread is specifically about BPs, so let's all stay on topic, okay?
