In the beginning of the poet you said she was 2.2 years old? Then later you described her non feeding behavior as teenage? A 2.2 year old bp weighing 630 gms? In any case you are trying to feed her too frequently. And this is just my opinion, switch to a10 to 12 day attempt to feed. If every week you are being unsuccessful the law of averages are working against you and her. Extend the time in between and consider feeding very late at night and in the complete dark. Mix a little 100% cypress mulch into the aspen and just back off the feeding attempts for the next 12 days. Definitely don't handle her or allow anyone else to handle her during this time. As a matter of fact I would start today and forget about that feeding you were going to do. Good luck and stay in peace and not pieces. Force feeding is way too stressful and you have so many other options right now.
