Completely understandable. Have faith she'll eat when she's ready. I personally have switched feeding my technique when it comes to my BPs. I actually let them dictate when I feed. I wait until I see them displaying "hunting behavior". What that means is I wait until I see their head poking out of their hide on consecutive nights. If I see that I offer on night three. So far 100% success rate. (knock on wood, hahaha)
I had one on a strike for about 3 months and he just recently ate. I hadn't offered in at least 6 weeks. But he showed the behavior I mentioned on back to back nights, so I offered on night three and he ate.
That being said, I've been in this hobby a long time and trust my ability to monitor their weight and body structure as well as my ability to "read" their body language.
So what works for me may not work for everyone, but it's been working for me and my BPs for about a year now using this technique.
