Im having that problem with my RTB, but I just go in touch her a few times, let her strike and then grab her. She's usually fine by that time and doesn't care about biting anymore. I feed every 7 days, but my buddy I got her from, he feeds all of his snakes every 3 days a small meal instead of feeding a large meal every 7-10 days so I also think she's adjusting from that feeding schedule.
