I'll be the first to say that my experience has been limited to my single ball python and a single kingsnake prior to that. I was unaware that feeding practices for balls differed from other breeds, so the expertise brought to bear on this forum trumps my personal experiences.

That said, I'll state that my ball has never hasn't shown any hesitancy or aversion to being fed outside his tank. He takes his meals quickly in the feeding cage, recognizes the feeding cage as where meals are provided, and allows me to return him to his tank without incident within half an hour after eating.

It's also important to note that Badoo spends a lot of time outside his tank, and so is likely more comfortable 'traveling'. He curls around my wrist during movies on the couch, while playing poker with friends, and occasionally while driving or shopping. He's been handled by nearly every visitor to my home and has always been content.

Again, this is just my personal experience keeping a single ball python. Those of you with experience keeping and breeding dozens of snakes have likely seen less agreeable behavior from your charges, and certainly have the more informed opinion.
