You are new and I understand that you were probably told to feed outside the enclosure however you are simply believing one the oldest myth out there, there is no such a thing ass cage aggression because an animal is fed in the cage, you actually put yourself at more risk moving an animal from one place to another while said animal is in feed mod which can start hours prior to feeding and last hours after feeding (just think about it), not to mention with animals such as BP it is actually stressful enough to lead to a refusal.
As for getting bit sooner or later it will happen and it will have nothing to do with feeding in the enclosure.
You were given very good advice and when asking for advice you should be willing to listen but ultimately it's on you and whether or not you want your animal to eat or prefer to believe a myth.
